Overview
AK8170B 1.
8V Single Clock Generatoｒ AK8170B Features Output Frequency Range: 38.
0MHz / 45.
0MHz (Selectable) Input Frequency: 27MHz Description The AK8170B is a single clock generator IC with an integrated PLL.
It can generate either a 38.
0MHz or 45.
0MHz clock from a 27MHz 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: 2.
4 mA （Typ.
） Output Load: 15pF (max.
) Supply Voltage: 1.

0MHz or 45.
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”: 38.
0MHz, “H”: 45.
0MHz “H”: active (1) (1) 6 CLKIN IN Clock input (27MHz) Place the AK8170B 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.
(1) The pin must be connected to either H or L.
Pull-up/pull-down resistor is not built into.
