ICS844003I-01 Overview
Description
The ICS844003I-01 is a 3 differential output LVDS Synthesizer designed to generate Ethernet referHiPerClockS™ ence clock frequencies and is a member of the HiPerClocks™ family of high performance clock solutions from ICS. Using a 19.53125MHz or 25MHz, 18pF parallel resonant crystal, the following frequencies can be generated based on the settings of 4 frequency select pins (DIV_SEL[A1:A0], DIV_SEL[B1:B0]): 625MHz, 312.5MHz, 156.25MHz, and 125MHz.
Key Features
- Three LVDS outputs on two banks, A Bank with one LVDS pair and B Bank with 2 LVDS output pairs
- Using a 19.53125MHz or 25MHz crystal, the two output banks can be independently set for 625MHz, 312.5MHz, 156.25MHz or 125MHz
- Selectable crystal oscillator interface or LVCMOS/LVTTL single-ended input
- VCO range: 490MHz to 680MHz
- RMS phase jitter @ 156.25MHz (1.875MHz
- 20MHz): 0.56ps (typical)
- 3.3V output supply mode
- 40°C to 85°C ambient operating temperature
