ICS840004-11 CRYSTAL-TO LVCMOS/LVTTL FREQUENCY SYNTHESIZER

The ICS840004-11 is a 4 output LVCMOS/ LVTTL Synthesizer optimized to generate HiPerClockS™ Ethernet reference clock frequencies and is a member of the HiPerClocks TM family of high performance clock solutions from ICS. Using a 25MHz, 18pF parallel resonant crystal, 125MHz and 62.5MHz can be generated based on one frequency select pin (F_SEL). The ICS840004-.
