Single Clock Generator - AKM
Description
ASAHI KASEI EMD CORPORATION
Single Clock Generator
AK8115
Features
Output Frequency Range: 27.
0MHz / 74.
17582MHz (Selectable) Input Frequency:
41.
538MHz
Description
The AK8115 is a single clock generator IC with an integrated PLL.
It can generate either a 27.
0MHz or 74.
17582MHz clock from a 41.
538MHz 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.

Description
Output clock frequency is selectable to 27.
0MHz or 74.
17582MHz 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.
17582MHz, “H”: 27.

CLKIN
IN
Clock input (41.
538MHz) Place the AK8115 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.
