General Description

The ICS8421004I-01 is a 4 output HSTL Synthesizer optimized to generate Ethernet HiPerClockS™ reference clock frequencies and is a member of the HiPerClocksTM family of high performance clock solutions from ICS.

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 ICS8421004I-01 uses ICS’ 3rd generation low phase noise VCO technology and can achieve 1ps or lower typical rms phase jitter, easily meeting Ethernet jitter requirements.

Key Features

  • Four HSTL outputs (VOHmax = 1.4V).
  • Selectable crystal oscillator interface or LVCMOS/LVTTL single-ended 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): 0.44ps (typical).
  • Power supply modes: Core/Output 3.3V/1.8V 2.5V/1.8V.
  • -40°C to 85°C ambient operating temperature.
