Description
The AK8130A is a member of AKEMD’s low power
multi clock generator family designed for a feature
rich DTV or STB, requiring a range of system
clocks with high performance. The AK8130A
generates different frequency clocks from a 27MHz
crystal oscillator and provides them to up to four
outputs configured by pin-setting. The on-chip
VCXO accepts a voltage control input to allow the
output clocks to vary by ±110 ppm for
synchronizing to the external clock system. Both
circuitries of VCXO and PLL in AK8130A are
derived from AKEMD’s long-term-experienced
clock device technology, and enable clock output
to perform low jitter and to operate with very low
current consumption. The AK8130A is available
in a 16-pin SSOP package.
