Description

Connection pin of resonator/clock input pin

Connection pin of resonator

Modulation enable pin/power down pin

Modulation rate setting pin

Down spread, SEL = “L” : Modulation rate − 1.0%

Down spread, SEL = “H” : Modulation rate − 2.0%

Down spread, SEL = “L” : Modulation rate ± 0.5%

Down spread, SEL = “H” : Modulation rate ± 1.0%

Non-modulated clock output pin

This pin becomes to“L” at power-down.

GND Pin

Modulated clock output pin

This pin becomes to“L” at power-down.

Power supply voltage pin
