6V Operating Temperature Range: -20 to +85℃ Package: 30-pin VSOP (Lead free) Description AK8135F 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.
AK8135F generates different frequency clocks from a 24.
576MHz crystal oscillator and provides them to seven outputs.
The on-chip VCFS (Voltage Controlled Frequency Synthesizer) accepts a voltage control input to allow the output clocks to vary by ±85 ppm for synchronizing to the external clock system.
Both circuitries of VCFS and PLL in AK8135F are derived from AKM’s long-term-experienced clock device technology, and enable clock output to perform low jitter and to operate with very low current consumption.
AK8135F is available in a 30-pin VSOP package.
