ASAHI KASEI EMD CORPORATION Single Clock Generator AK8111 Features Description The AK8111 is a single clock generator IC with an integrated PLL. It can generate either a 12.288MHz or a 24.576MHz 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. Output Frequency Range: 12.288MHz / 24.576MHz (Selectable) Input Frequency: 27MHz Low Jitter Performance: 15 ps (Typ.) Period, 1 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 IEEE1394 Audio Block Diagram AK8111 Single Clock Generator MS0453-E-05 Feb-08 -1- The brand name of AKEMD's IC's AK8111 Pin Descriptions Package: 6-Pin SON (Top View) *lead-free Pin No. Pin Name Pin Type 1 VDD -- Power Supply 2 VSS -- Ground 3 CLKOUT OUT 4 OE IN 5 FSEL IN Description Clock output 6 CLKIN Output clock frequency is selectable to 12.288MHz or 24.576MHz by setting the FSEL pin. In power down mode (OE = "L"), this pin is "L". CLKOUT output enable control "L": CLKOUT="L" and power down. Clock frequency select "L": 24.576MHz, "H": 12.288MHz (1) "H": active (1) Clock input (27MHz) Place the AK8111 in power down (OE = "L") mode when an input clock is not supplied. Unstable input to the CLKIN causes the unstable CLKOUT signal. DC input to the CLKIN also causes the unstable CLKOUT signal. IN (1) Internal pull down 100k (Typ.)

These are stress ratings only. Functional operation of the device at these or any other conditions beyond those indicated under "Recommended Operating Conditions" is not implied. Exposure to absolute-maximum-rating conditions for extended periods may affect device reliability. Electrical parameters are guaranteed only over the recommended operating temperature range. ESD Sensitive Device This device is manufactured on a CMOS process, therefore, generically susceptible to damage by excessive static voltage. Failure to observe proper handling and installation procedures can cause damage. AKEMD recommends that this device is handled with appropriate precautions.
