AK8135S Datasheet Multi Clock Generator

Manufacturer: AKM (Asahi Kasei Microdevices)

Overview: AK8135S Preliminary Low Power Multiclock Generator with VCFS AK8135S.

General Description

AK8135S is a member of AKM’s low power multi clock generator family designed for Recorders, DTVs or STBs, requiring a range of system clocks with high performance.

AK8135S generates different frequency clocks from a 30.000MHz crystal oscillator and provides them to eight outputs.

Th e on-chip VCFS (Voltage Controlled Frequency Synthesizer) accepts a voltage control input to allow the output clocks to vary by ±120/135 ppm for synchronizing to the external clock system.
