Single Clock Generator - AKM
Description
ASAHI KASEI EMD CORPORATION
Single Clock Generator
AK8118
Features
Output Frequency Range: 40.
5MHz / 32.
0MHz (Selectable) Input Frequency:
27MHz
Description
The AK8118 is a single clock generator IC with an integrated PLL.
It can generate either a 40.
5MHz or a 32.
0MHz 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: -20 to +85℃ Package: 6-pin SON (lead-free) Body Size 2.

Description
Output clock frequency is selectable to 40.
5MHz or 32.
0MHz 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”: 40.
5MHz, “H”: 32.
0MHz “H”: active (1) (1)

CLKIN
IN
Clock input (27MHz) Place the AK8118 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.
