The ICS1893CF is a low-power, physical-layer receiver that supports 10Base-T and 100Base-TX IEEE 8802.3 standards.

The ICS650-27 is a low cost, low jitter, high performance clock synthesizer for networking applications. Using analog Phase-Locked Loop (PLL) techniques, the device accepts a 12.5 MHz or 25 MHz clock or fundamental mode crystal input to produce multiple output clocks for networking chips, PCI devices, SDRAM, and ASICs. The ICS650-27 outputs all have zero ppm synthesis error. The ICS650-27 is pin compatible and functionally equivalent to the ICS650-07. It is a performance upgrade and is recommended for all new 3.3V designs.

The ICS342 is a low cost, dual-output, field programmable clock synthesizer.

The MK1432 and MK1434 are low cost, high performance triple clock synthesizers for green PC and local bus desktop and notebook applications. Using analog Phase-Locked Loop (PLL) techniques, the devices accept a 14.318 MHz crystal input to produce multiple output clocks up to 100 MHz. They provide selectable 2XCPU and CPU, selectable local bus clock, ISA clock, and one fixed peripheral clock. The chips support PCI and VL buses. The fixed clock is either 24MHz or 40MHz. The devices can operate at 5V or 3.3V up to and including 80MHz on the 2XCPU clock. The Power Saving pin causes the CPU clocks to smoothly transition to 33.33 MHz for Pentiums, and 16.67 MHz for 486DX4. In addition, a single pin can be made to slow DX2s to 8 MHz.

ICS94229 is a programmable system clock chip that supports AMD - K7™ processors and is suitable for VIA KT266-style chipsets. It features programmable output frequency, programmable output rise/fall time, programmable slew and skew control, real-time system reset output, EMI control, and watchdog timer technology.

The MK1410 and MK1411 are the ideal way to generate clocks for NTSC/PAL video encoders and decoders. The devices store two or four popular frequencies for NTSC and PAL. The chips save component count, board space, and cost over surface mount crystals and oscillators in an 8-pin SOIC, and increase reliability by eliminating one or two mechanical devices from the board. The power down pin turns off the device, drawing less than 20µA. MicroClock offers many other clocks for computers and computer peripherals.

ICS601-01 is a low cost, low phase noise, high performance clock synthesizer for any applications that require low phase noise and low jitter. It is ICS's lowest phase noise multiplier, and also the lowest CMOS part in the industry.

The ICS840002-01 is a LVCMOS/LVTTL frequency synthesizer optimized to generate Ethernet reference clock frequencies. It uses a 25MHz 18pF parallel resonant crystal, and can generate frequencies of 156.25MHz, 125MHz, and 62.5MHz based on the frequency select pins (F_SEL1:0). The ICS840002-01 utilizes ICS' 3rd generation low phase noise VCO technology and can achieve 1ps or lower typical random rms phase jitter, meeting Ethernet jitter requirements.

ICS9248-195 is a frequency generator and integrated buffers produced by Integrated Circuit Systems, Inc., which is suitable for PENTIUM II/IIITM and K6 processors. Its main features include support for up to 137MHz frequency, 97MHz to support high-end AMD processors, power management support, frequency selection, and so on.

The ICS8427-02 is a general purpose, six LVHSTL output high frequency synthesizer and a member of the HiPerClockS™ family of High Performance Clock Solutions from ICS. It supports a very wide output frequency range of 15.625MHz to 500MHz. The device powers up at a default output frequency of 200MHz with a 16.6667MHz crystal interface, and the frequency can then be changed using the serial programming interface to change the M feedback divider and N output divider. Frequency steps as small as 125kHz can be achieved using a 16.6667MHz crystal and the output divider set for ÷16. The low jitter and frequency range of the ICS8427-02 make it an ideal clock generator for most clock tree applications.

The MK1442/3 are the ideal way to generate clocks for desktop computer motherboards and LAN workstations. Using analog Phase-Locked Loop (PLL) techniques, the devices accept a 14.318 MHz crystal input to produce multiple output clocks up to 100 MHz. They provide 2XCPU, CPU, floppy controller, keyboard, system, SCSI and Ethernet clocks. The MK1442/3 are perfect for new Pentium™ Processor, PCI bus and 486 systems. The devices can operate at 5V or 3.3V up to and including 80MHz on the CPU clock. The devices are identical except the MK1442 has an Output Enable (OE) pin that tri-states all outputs when taken low, and the MK1443 has an extra 14.318 MHz clock.

This product is a low cost 20-pin frequency generator with low power consumption and high reliability.
