DESCRIPTION

· AK8135F is a low-power multi-clock generator designed for recorders, DTVs, or STBs, providing high-performance system clocks.
· It generates various frequency clocks from a 24.576 MHz crystal oscillator and delivers them to seven outputs.
· The on-chip VCFS allows output clocks to vary by ±85 ppm for synchronization with external clock systems.
· The device features low jitter and operates with minimal current consumption, packaged in a 30-pin VSOP.

FEATURES

· 24.576 MHz crystal input with one 24.576 MHz reference output.
· Selectable clock frequencies: 24.576 MHz, 24.99972 MHz, 33.332965 MHz, and 27.000 MHz.
· Built-in two VCFS with a pull range of ±85 ppm.
· Low jitter performance: 150 psec period jitter and 400 psec long-term jitter.
· Low current consumption: 24 mA at 3.3V.
· Low C/N output: 72 dB at REF1-4.
· Supply voltage: 3.0–3.6V, operating temperature range: -20 to +85℃.

APPLICATIONS

· HDD, DVD, BD Recorder.
· DTV.
· Set-Top-Boxes.
