The MAX1777/MAX1977/MAX1999 are dual step-down, switch-mode power-supply (SMPS) controllers that generate logic-supply voltages in battery-powered systems. These devices feature two pulse-width modulation (PWM) controllers, adjustable from 2V to 5.5V or fixed at 5V and 3.3V.

The MAX16060/MAX16061/MAX16062 are 1% accurate, quad-/hex-/octal-voltage µP supervisors in a small thin QFN package. These devices provide supervisory functions for complex multivoltage systems. The MAX16060 monitors four voltages, the MAX16061 monitors six voltages, and the MAX16062 monitors eight voltages. These devices offer independent outputs for each monitored voltage along with a reset output that asserts whenever any of the monitored voltages fall below their respective thresholds (down to 0.4V) or the manual reset input is asserted. The reset output remains asserted for the reset timeout after all voltages are above their respective thresholds and the manual reset input is deasserted. The minimum reset timeout is internally set to 140ms or can be adjusted with an external capacitor. All open-drain outputs have internal 30µA pullups that eliminate the need for external pullup resistors. However, each output can be driven with an external voltage up to 5.5V. Other features offered include a manual reset input, a tolerance pin for selecting 5% or 10% input thresholds, and a margin enable function for deasserting the outputs during margin testing. An additional feature is a watchdog timer that asserts RESET when the watchdog timeout period (1.6s typ) is exceeded. The watchdog timer can be disabled by leaving WDI unconnected. These devices are offered in 16-, 20-, and 24-pin thin QFN packages (4mm x 4mm) and are fully specified from -40°C to +1°C.

The MAX1036–MAX1039 low-power, 8-bit, multichannel, analog-to-digital converters (ADCs) feature internal track/hold (T/H), voltage reference, clock, and an I2C-compatible 2-wire serial interface. These devices operate from a single supply and require only 350µA at the maximum sampling rate of 188ksps. Auto- Shutdown™ powers down the devices between conver- sions reducing supply current to less than 1µA at low throughput rates. The MAX1036/MAX1037 have four ana- log input channels each, while the MAX1038/MAX1039 have twelve analog input channels. The analog inputs are software configurable for unipolar or bipolar and single- ended or pseudo-differential operation. The full-scale analog input range is determined by the internal reference or by an externally applied reference voltage ranging from 1V to VDD. The MAX1037/ MAX1039 feature a 2.048V internal reference and the MAX1036/MAX1038 feature a 4.096V internal reference. The MAX1036/MAX1037 are available in 8-pin SOT23 packages. The MAX1038/MAX1039 are available in 16- pin QSOP packages. The MAX1036–MAX1039 are guar- anteed over the extended industrial temperature range (-40°C to +85°C). Refer to MAX1136–MAX1139 for 10-bit devices and to the MAX1236–MAX1239 for 12-bit devices.

This document is an introduction to the product DS2433. This product is a 4kb 1-Wire® EEPROM with 4096 bits Electrically Erasable Programmable Read-Only Memory (EEPROM). It has a unique 64-bit registration number, which ensures absolute identity.

MAX3800 is a +3.3V adaptive cable equalizer and cable driver implemented together on a single chip

The MAX3801 is a +3.3V adaptive cable equalizer designed for coaxial and twin-axial cable point-to-point communications applications. The equalizer includes differential CML data inputs and outputs, a loss-of-sig- nal (LOS) output, and a cable integrity monitor (CIM) output.

The MAX3980 quad equalizer provides compensation for transmission medium losses for four “lanes” of digital NRZ data at a 3.125Gbps data rate in one package. It is tailor-made for 10-Gigabit Ethernet (10GbE) backplane applications requiring attenuation of noise and jitter that occur in communicating from MAC to PMD or from MAC to Switch. In support of the IEEE-802.3ae for the XAUI interface, the MAX3980 adaptively allows XAUI lanes to reach up to 40in (1.0m) on FR-4 board material. The equalizer has 100Ω differential CML data inputs and outputs. The MAX3980 is available in a 44-pin exposed-pad QFN package. The MAX3980 consumes only 700mW at +3.3V or 175mW per channel.

The MAX3802 is a single-chip quad adaptive cable equalizer and cable driver designed for coaxial and twin-axial cable point-to-point scrambled data communications applications.

The MAX3784/MAX3784A 5Gbps equalizers provide compensation for transmission-medium losses in up to 40in of FR-4. They are optimized for short-run length and balanced codes such as 8b10b, as found in multiplexed 1.25Gbps Ethernet systems and 4.25Gbps Fibre Channel. The equalizers use differential CML data inputs and outputs. A standby mode reduces power consumption when the parts are not in use. The MAX3784/ MAX3784A are available in a 4mm × 4mm, 16-pin QFN package that consumes only 185mW at +3.3V.

The MAX3785 6.25Gbps 1.8V PC Board Equalizer is a product of Maxim Integrated, which operates from a single 1.8V supply and compensates for transmission medium losses encountered with FR-4 transmission lines. This product is optimized for low-voltage, high-density, DC-coupled interconnections between the line card and switch card, allowing a system upgrade path while maintaining a legacy rate of 2.5Gbps to 3.125Gbps. The product is roughly the size of two 0603 passive components, which makes it easy to place and route.

The MAX3804 driver with integrated analog equalizer compensates up to 20dB of loss at 5GHz. It is designed to ensure PC board signal integrity up to 12.5Gbps, where frequency-dependent skin effect and dielectric losses typically produce unacceptable amounts of inter-symbol interference. The MAX3804 can extend the practical chip-to-chip transmission distance for 10Gbps NRZ serial data up to 30in (0.75m) on FR-4, and it significantly decreases deterministic jitter. Residual jitter after equalization for 10.7Gbps signals is typically 24psP-P on the maximum path length. The MAX3804 is ideal for 10Gbps chip-to-chip serial interconnections on inexpensive FR-4 material. Its 3mm×3mm package affords optimal placement and routing flexibility. It has separate VCC connections for internal logic and current-mode logic (CML) I/O. This allows the CML input and output to be referenced to isolated supplies, providing independent DC-coupled interfacing to 1.8V, 2.5V, or 3.3V ICs. Eight discrete levels of input equalization can be selected through a digital control input, enabling the equalizer to be matched to a range of transmission line path loss. When correctly set to match the path loss, the MAX3804 provides optimal performance over a wide range of data rates and formats. Applications include OC-192 and 10Gb Ethernet switches and routers, OC-192 and 10Gb Ethernet serial modules, high-speed signal distribution.

The MAX3803 is a high-performance differential line equalizer from Maxim Integrated Products. It has a small size of 2mm x 2.5mm and supports 1Gbps to 3.2Gbps transmission speed. It is suitable for backplane interconnect, rack-to-rack interconnect and other applications.

The MAX3983 is a quad copper-cable signal conditioner from Maxim Integrated. It operates from 2.5Gbps to 3.2Gbps and provides compensation for 4x copper InfiniBand and 10Gbase-CX4 Ethernet links, allowing spans of 20m with 24AWG and 15m with 28AWG. The cable driver section provides four selectable preemphasis levels. The input to the cable driver compensates for up to 0.5m of FR4 circuit board material. The cable receiver section provides additional fixed input equalization while offering selectable preemphasis to drive FR4 circuit boards up to 0.5m. The MAX3983 also features signal detection on all eight inputs and internal loopback that allows for diagnostic testing. It is packaged in a 10mm x 10mm, 68-pin QFN and operates from 0°C to +85°C.

The MAX3982 is a single-channel, copper-cable preemphasis driver that operates from 1Gbps to 4.25Gbps. It provides compensation for copper links, such as 4.25Gbps Fibre Channel, allowing spans of up to 15m with 24AWG. The cable driver provides four selectable preemphasis levels. The input compensates for up to 10in of FR4 circuit board material at 4.25Gbps. The MAX3982 also features SFP-compliant loss-of-signal detection with selectable sensitivity and TX_DISABLE. Selectable output swing reduces EMI and power consumption. It is packaged in a 3mm x 3mm, 16-pin thin QFN and operates from 0°C to +85°C temperature range.

The MAX3787 is a 1Gbps to 12.5Gbps equalization network that compensates for transmission medium losses encountered with FR4 and cables.
