SCG2070 Individual Features:

• Input References (Pin #8) at 19.44 MHz.

• Oscillator Output (Pin #9) equals Reference

Output (Pin #1)

The SCG2070 is designed to provide two

output frequencies that are equal. The

Reference Output is actually a second

Oscillator Output. SCG2070 is available

with either 77.76 MHz outputs or with

51.84 MHz outputs. The LOL alarm is

designed to tolerate 1

µs p-p

of jitter on the reference. Jitter greater than

µs p-p will result in LOL alarm pulses.
