Overview
ASAHI KASEI EMD CORPORATION
Single Clock Generator
AK8117
Features
Output Frequency Range: 38.
000MHz / 38.
6667MHz (Selectable) Input Frequency:
27MHz
Description
The AK8117 is a single clock generator IC with an integrated PLL.
It can generate either a 38.
000MHz or a 38.
6667MHz 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.
3mA (Typ.
) Output Load: 15pF (max.
) Supply Voltage: 2.

Description
Output clock frequency is selectable to 38.
000MHz or 38.
6667MHz 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”: 38.
000MHz, “H”: 38.
6667MHz Clock input (27MHz) Place the AK8117 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.
