NOTICE - The following device(s) are recommended alternatives:

The 840002I-01 is a two 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 two frequency select pins (F_SEL[1:0]): 156.25MHz, 125MHz, and 62.5MHz. The 840002I-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 840002I-01 is packaged in a small 16-pin TSSOP package.

Features

  • Two LVCMOS/LVTTL outputs@ 3.3V, 17Ω typical output impedance
  • Selectable crystal oscillator interface or LVCMOS/LVTTL single-ended TEST_CLK
  • Supports the following output frequencies: 156.25MHz, 125MHz and 62.5MHz
  • Output frequency range: 56MHz to 175MHz
  • VCO range: 560MHz to 700MHz
  • Output skew: 12ps (maximum)
  • RMS phase jitter at 156.25MHz, (1.875MHz to 20MHz): 0.47ps (typical)
