General Description
The ICS843156 is a high frequency clock generator. The ICS843156
uses an external 25MHz crystal to synthesize 156.25MHz clock. The
ICS843156 has excellent cycle-to-cycle and RMS period jitter performance.
The ICS843156 operates at full 3.3V and 2.5V, or mixed 3.3V/2.5V
operating supplies and is available in a fully RoHS compliant 32-lead
VFQFN package
