General Description

The ICS8422002I-01 is a 2 output LVHSTL Synthesizer optimized to generate Ethernet HiPerClockS™ reference clock 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 ICS8422002I-01 uses IDT’s 3rd generation low phase noise VCO technology and can achieve 1ps or lower typical rms phase jitter, easily meeting Ethernet jitter requirements.

Key Features

  • Two LVHSTL outputs (VOHmax = 1.2V) 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 Available in both standard (.
