CXA3106Q
(2) Recommended TTL I/O circuit
The peripheral circuits mainly use TTL for digital input and output. Of course, PECL and TTL can also be
mixed.

1 Unless otherwise specified, all capacitors are 0.1µF.
2 Vary the external resistor and capacitor values of the
UNLOCK output as necessary.

3 This external resistor (1.6kΩ) should be a metal film
resistor in consideration of temperature characteristics.
4 The loop filter's capacitors and resistor should also be
temperature compensated.
