DP83849C PHYTER® DUAL is a dual port 10/100 Mb/s Ethernet physical layer transceiver from National Semiconductor Corporation for commercial temperature applications
This document introduces the features and characteristics of the LM3406/06HV product. The LM3406/06HV is a monolithic switching regulator designed to deliver constant currents to high power LEDs. It is ideal for automotive, industrial, and general lighting applications. The product also supports pulse width modulation (PWM) dimming, which can be achieved using a dedicated logic pin or by PWM of the power input voltage.
LM3410 is a high frequency, high performance LED driver from Texas Instruments, available in 5 pin SOT23, 6 pin LLP and 8 pin eMSOP packages. It features an internal 170 mΩ NMOS switch that can drive 2.8A typical peak currents. The switching frequency can be internally set to either 525 kHz or 1.60 MHz, allowing for the use of extremely small surface mount inductors and chip capacitors. Even though the operating frequency is high, efficiencies up to 88% are easy to achieve. The LM3410 also features an ultra-low standby current of 80 nA. It utilizes current-mode control and internal compensation to provide high-performance over a wide range of operating conditions. Additional features include dimming, cycle-by-cycle current limit, and thermal shutdown.
LMH2180 is a high speed dual clock buffer designed for portable communications and applications requiring multiple accurate multi-clock systems. It integrates two 75 MHz low noise buffers with independent shutdown pins into a small package.
The DP83865 is a fully featured Physical Layer transceiver with integrated PMD sublayers to support 10BASE-T, 100BASE-TX and 1000BASE-T Ethernet protocols. The DP83865 is an ultra low power version of the DP83861 and DP83891. It uses advanced 0.18 um, 1.8 V CMOS technology, fabricated at National Semiconductor’s South Portland, Maine facility. The DP83865 is designed for easy implementation of 10/100/1000 Mb/s Ethernet LANs. It interfaces directly to Twisted Pair media via an external transformer. This device interfaces directly to the MAC layer through the IEEE 802.3u Standard Media Independent Interface (MII), the IEEE 802.3z Gigabit Media Independent Interface (GMII), or Reduced GMII (RGMII). The DP83865 is a fourth generation Gigabit PHY with field proven architecture and performance. Its robust performance ensures drop-in replacement of existing 10/100 Mbps equipment with ten to one hundred times the performance using the existing networking infrastructure.
The LM4308 device adapts a 18-bit CPU style display interfaces to a MPL-2 SLVS differential serial link for displays. Two chip selects support a main and sub display up to and beyond 640 x 480 pixels. A mode pin configures the device as a Master (MST) or Slave (SLV). Both WRITE and READ operations are supported. CPU interface widths below 18-bits are supported by tieing unused inputs to a static level. The differential line drivers and receivers conform to the JEDEC SLVS Standard. When noise is picked up as common-mode, it is rejected by the receivers. This is further enhanced with the 50 Ohm output impedance of the drivers. The 100 Ohm termination is integrated into the receivers. Data integrity is insured with a 5-bit CRC field. CRC checking is done for both WRITE and READ operations. An Error (ERR) pin reports the occurrence of an error. A Write Only mode is also provided. The interconnect is reduced from 23 signals to only 4 active signals with the LM4308 chipset easing flex interconnect design, size constraints and cost. A low power sleep state entered when the PD* inputs are driven low.
The DS90UR241/DS90UR124 is a 5-43MHz DC-balanced 24-bit LVDS serializer and deserializer. The device translates a 24-bit parallel bus into a fully transparent data/control LVDS serial stream with embedded clock information, eliminating the skew problems between parallel data and clock paths. It saves system cost by narrowing data paths, which in turn reduce PCB layers, cable width, and connector size and pins.
LM3151/2/3 SIMPLE SWITCHER® CONTROLLER, 42V Synchronous Step-Down is an easy-to-use and simplified step down power controller capable of providing up to 12A of output current in a typical application.
The LM6181 is a 100 MHz current feedback amplifier with a slew rate of 2000V/µs. It is ideal for data acquisition, high speed ATE, and precision pulse amplifier applications.
The LM3915 is an integrated circuit that can sense analog voltage levels and drive ten LEDs, LCDs or vacuum fluorescent displays, providing a logarithmic 3 dB/step analog display.
The DP84240 and DP84244 are octal TRI-STATE drivers designed for heavy capacitive load applications such as fast data buffers or as memory address drivers. The DP84240 is an inverting driver which is pin-compatible with both the 74S240 and AM2965. The DP84244 is a non-inverting driver which is pin-compatible with the 74S244 and AM2966. These parts are fabricated using an oxide isolation process for much faster speeds and are specified for 250 pF and 500 pF load capacitances. TRI-STATE is a registered trademark of National Semiconductor Corp.
