ICS844023I Description
The ICS844023I is an Ethernet Clock Generator and a member of the HiPerClocksTM family of high HiPerClockS™ performance devices from ICS. The ICS844023I uses an 18pF parallel resonant crystal over the range of 24.5MHz - 34MHz. For Ethernet applications, a 25MHz crystal is used to generate 250MHz.
ICS844023I Key Features
- One Differential LVDS output
- Crystal oscillator interface, 18pF parallel resonant crystal (24.5MHz
- 34MHz)
- Output frequency range: 245MHz
- 340MHz
- VCO range: 490MHz
- 680MHz
- RMS phase jitter @ 250MHz, using a 25MHz crystal (1.875MHz
- 20MHz): 0.38ps (typical)
