Single Clock Generator
AK8116
Features
Output Frequency Range: 27. 0MHz / 74. 25MHz (Selectable) Input Frequency:
33. 75MHz
Description
The AK8116 is a single clock generator IC with an integrated PLL. It can generate either a 27. 0MHz or a 74. 25MHz clock from a 33. 75MHz 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. 8mA (Typ. ) Output Load: 15pF (max. ) Supply Voltage: 2. 7 – 3. 6V Operating Temperature Range: -20 to +85℃ Package: 6-pin SON (lead-free) Body Size 2. 6mm x 1. 6mm
Applications
High Definition Digital Video Camera

Description
Output clock frequency is selectable to 27. 0MHz 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. Clock frequency select “L”: 74. 25MHz, “H”: 27. 0MHz “H”: active (1) (1)

IN
Clock input (33. 75MHz) Place the AK8116 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.
