Voltage Controlled Crystal Oscillators (VCXO’s)

Pin #

Symbol

Name/Function

1

VCXO: Control Voltage to modulate frequency.

2

Tri-state

TTL logic low disables output. TTL logic high

or no connection enables output frequency.

3

GND

Circuit and case ground

4

Output

Output waveform

5

TTL/CMOS

TTL logic low provides waveform symmetry

for CMOS. TTL logic high or no connection

provides waveform symmetry for TTL.

6

Supply Voltage, 5 V ±10% or 3.3V ±10%
