ICS840004I-01 - Integrated Circuit Systems

ICS840004I-01 CRYSTAL-TO LVCMOS/LVTTL FREQUENCY SYNTHESIZER

The ICS840004I-01 is a 4 output LVCMOS/LVTTL 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_SEL1:0): 15.

Features

• Four LVCMOS/LVTTL outputs, 15Ω typical output impedance
• Selectable crystal oscillator interface or LVCMOS single-ended input
• Supports the following output frequencies: 156.25MHz, 125MHz and 62.5MHz
• RMS phase jitter @ 156.25MHZ (1.875MHz - 20MHz): 0.52ps (typical)
• Output supply modes: Core/Output 3.3V/3.3V 3.3V/2.5V 2.5V/2.5V
• -40°C to 85°C ambient operating temperature GENERAL DESCRIPTION The ICS840004I-01 is a 4 output LVCMOS/LVTTL Synthesizer optimized to generate Ethernet HiPerClockS™ reference clock frequencies and is a member of the HiPerClocksTM family of high performance clo.
