844002AG-01T

FEMTOCLOCKS– CRYSTAL-TOLVDS FREQUENCY SYNTHESIZER ICS844002-01 Features • • • • • • • • Two differential LVDS outputs Selectable crystal oscillator interface or single-ended LVCMOS/LVTTL input Supports the following output frequencies: 156.25MHz, 125MHz, 62.5MHz VCO range: 560MHz – 680MHz RMS phase jitter @ 156.25MHz, using a 25MHz crystal (1.875MHz – 20MHz): 0.41ps (typical) Full 3.3V and 2.5V supply modes 0°C to 70°C ambient operating temperature Available in both standard (RoHS 5) and lead-free (RoHS 6) packages Description The ICS844002-01 is a 2 output LVDS Synthesizer optimized to generate Ethernet reference clock HiPerClockS™ frequencies and is a member of the HiPerClocksTM family of high performance clock solutions from IDT. Using a 25MHz, 18pF parallel resonant crystal, the following frequencies can be generated based on the 2 frequency select pins (F_SEL[1:0]): 156.25MHz, 125MHz and 62.5MHz. The ICS844002-01 uses IDT’s 3rd generation low phase noise VCO technology and can achieve
