AK8146A

ASAHI KASEI MICRODEVICES Low Power Multiclock Generator AK8146A Features 24.0MHz External Input or Crystal Input Clock out Frequencies: - 24.000MHz - 20.48MHz 4.000MHz Low Jitter Performance - Period Jitter: 25 psec (Typ.) at CLK1-2 Low Current Consumption: 5.0mA (Typ.) at 3.3V Supply Voltage: 3.0 – 3.6V Operating Temperature Range: -20 to +85℃ Package: 8-pin MSOP (Lead free) Description The AK8146A is a low power multi clock generator which generates different frequency clocks from a 24MHz crystal oscillator or external clock input. It provides up to three outputs. The PLL in the AK8146A is derived from AKM’s high-performance clock device technology, enabling the clock output to perform with low jitter and to operate with very low current consumption. The AK8146A is available in an 8-pin MSOP package.
