Description
AK8135F is a member of AKMs 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 AKMs 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.
