Description

The AK8113 is a single clock generator IC with an integrated PLL. It can generate either a

74.17582MHz or a 74.25MHz 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.

Clock output

Output clock frequency is selectable to 74.17582MHz or 74.25MHz 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. “H”: active

Clock frequency select

“L”: 74.25MHz, “H”: 74.17582MHz

6 CLKIN IN

Clock input (27MHz)

Place the AK8113 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.

Note

(1) Stress beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.

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.
