AK8145

ASAHI KASEI EMD CORPORATION 27.0MHz VCXO Clock Genrerator AK8145 Features 27.0MHz Crystal Input One 27.0MHz-Refrence output Built-in VCXO - Pull Range +/-100ppm Low Jitter Performance - Period Jitter: 100 psec (p-p,Typ.) - Long term Jitter: 150 psec (1000cycles,p-p,Typ.) Low Current Consumption: 4.5mA (Typ.) at 3.3V 60μA（Max.） at Power down Supply Voltage: 3.0 – 3.6V Operating Temperature Range: -20 to +85℃ Package: 8-pin MSOP (Lead free) Description The AK8145 is a low power, low jitter VCXO IC. AK8145 accepts 27MHz fundamental crystal input and produces a low-jitter output at the same frequency. 0V to +3.3V signal to VIN is used to control the output clock frequency. The AK8145 is available in a 8-pin MSOP package.
