Single Clock Generator - AKM
Description
ASAHI KASEI EMD CORPORATION
Single Clock Generator
AK8119A
Features
Output Frequency Range: 40.
5MHz / 36.
0MHz (Selectable) Input Frequency:
12MHz
Description
The AK8119A is a single clock generator IC with an integrated PLL.
It can generate either a 40.
5MHz or 36.
0MHz clock from a 12MHz master clock input frequency.
Through pin control, the output can be enabled or disabled, and the frequency can be changed.
The 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.
0mA (Typ.
) Output Load: 15pF (max.
) Supply Voltage: 2.
7 – 3.
6V Operating Temperature Range: -20 to +85℃ Package: 6-pin USON (lead-free)

Clock input (12MHz) Place the AK8119A 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.
