AK8135C generates different frequency clocks from a 24.576MHz crystal oscillator and provides them to seven outputs. The on-chip VCFO (Voltage Controlled Frequency Oscillator) accepts a voltage control input to allow the output clocks to vary by ±96 ppm for synchronizing to the external clock system. Both circuitries of VCFO and PLL in AK8135C 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. AK8135C is available in a 30-pin VSOP package. Applications HDD, DVD, BD Recorder DTV Set-Top-Boxes...
