ICS843252 Description
The ICS843252 is a 2 differential output LVPECL 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 (SEL[A1:A0], SEL[B1:B0]): 625MHz, 312.5MHz,...
ICS843252 Key Features
- Two 3.3V differential LVPECL output pairs

- Crystal oscillator interface
- VCO range: 490MHz to 680MHz
- RMS phase jitter @ 156.25MHz (1.875MHz
- 20MHz): 0.47ps (typical)
- Full 3.3V supply mode
- 0°C to 70°C ambient operating temperature
- Industrial temperature available upon request
- Available in both standard and lead-free RoHS-pliant packages
