840004AG-01LF - Renesas Electronics
Description: The 840004-01 is a 4 output LVCMOS/LVTTL Synthesizer optimized to generate Ethernet reference clock frequencies. Using a 25MHz, 18pF parallel resonant crystal, the following frequencies can be generated based on the 2 frequency select pins (F_SEL1:0): 156.25MHz, 125MHz, and 62.5MHz. The 840004-01 uses IDT's 3rd generation low phase noise VCO technology and can achieve 1ps or lower typical random rms phase jitter, easily meeting Ethernet jitter requirements. The 840004-01 is packaged in a small 20-pin TSSOP
