AK8170B

AK8170B 1.8V Single Clock Generatoｒ AK8170B Features Output Frequency Range: 38.0MHz / 45.0MHz (Selectable) Input Frequency: 27MHz Description The AK8170B is a single clock generator IC with an integrated PLL. It can generate either a 38.0MHz or 45.0MHz clock from a 27MHz master clock input frequency. Through pin control, the output can be enabled or disabled, and the frequency can be changed. The high performance PLL locks to the master clock input, generating a low jitter, highly accurate clock output without an external crystal. Low Jitter Performance: 15 ps （Typ.） Period, 1σ Low Current Consumption: 2.4 mA （Typ.） Output Load: 15pF (max.) Supply Voltage: 1.7 – 1.9V Operating Temperature Range: -20℃ to +85℃ Package: 6-pin USON (lead-free) Body Size 1.4mm x 1.4mm Applications Digital Still Camera Block Diagram VDD CLKIN Input Buffer PLL Output Buffer CLKOUT OE FSEL VSS AK8170B Single Clock Generator MS1063-E-00 May-11 http://www.Datasheet4U.com -1- AK8170B Pin Descriptions 1.VDD 2.VSS 3.CLKOUT 6.CLKIN 5.FSEL 4.OE Package: 6-Pin USON (Top View) *lead-free Pin No. 1 2 3 4 5 Pin Name VDD VSS CLKOUT OE FSEL Pin Type --OUT IN IN Power Supply Ground Clock output Description Output clock frequency is selectable to 38.0MHz or 45.0MHz by setting the FSEL pin.
