6V Operating Temperature Range: -20 to +85℃ Package: 20-pin SSOP (Lead free, Halogen free) VDD Description The AK8136A is a member of AKM’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 AK8136A generates different frequency clocks from a 27MHz crystal oscillator and provides them to up to four outputs configured by register-setting.
The on-chip VCXO accepts a voltage control input to allow the output clocks to vary by ±150 ppm for synchronizing to the external clock system.
Both circuitries of VCXO and PLL in AK8136A 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.
The AK8136A is available in a 20-pin SSOP package.
