描述
The 843156I is a high frequency clock generator. The 843156I uses an external 25MHz crystal to synthesize 156.25MHz clock. The 843156I has excellent cycle-to-cycle and RMS period jitter performance. The 843156I 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.
