AK8131C

ASAHI KASEI EMD CORPORATION Low Power Multiclock Generator with VCXO AK8131C Features 27MHz Crystal Input Clock out Frequencies: REFOUT: 27.000MHz CLK1: 33.000MHz CLK2: 33.000MHz CLK3: 27.000MHz CLK4: 27.000MHz Built-in VCXO - Pull Range: ±100ppm (Min.) Low Jitter Performance - Period Jitter : 120 psec (Typ.) at CLK1/CLK2 - Long Term Jitter : 160 psec (Typ.) at REFOUT/CLK3/4 Low Current Consumption: 10.0mA (Typ.) at 3.3V Supply Voltage: 3.0 – 3.6V Operating Temperature Range: -20 to +85℃ Package: 16-pin SSOP (Lead free) Description The AK8131C 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 on-chip VCXO accepts a voltage control input to allow the output clocks to vary by ±100 ppm for synchronizing to the external clock system. Both circuitries of VCXO and PLL in AK8131C 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 AK8131C is available in a 16-pin SSOP package.
