AK8112

ASAHI KASEI EMD CORPORATION Single Clock Generator AK8112 Features Output Frequency Range: 33.75MHz / 67.5MHz (Selectable) Input Frequency: 27MHz Description The AK8112 is a single clock generator IC with an integrated PLL. It can generate either a 33.75MHz or a 67.5MHz clock from a 27MHz master clock input frequency. Through pin control, the output can be enabled or disabled, the frequency can be changed, and the device can be placed in a power-down mode. A 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: 3.5mA (Typ.) Output Load: 15pF (max.) Supply Voltage: 2.7 – 3.6V Operating Temperature Range: -10 to +80℃ Package: 6-pin SON (lead-free) Body Size 2.6mm x 1.6mm Applications Digital Still Camera Block Diagram AK8112 Single Clock Generator MS0516-E-03 -1- Feb-08 http://www.Datasheet4U.com AK8112 The brand name of AKEMD’s IC’s Pin Descriptions Package: 6-Pin SON (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 33.75MHz or 67.5MHz by setting the FSEL pin.
