SCG2020 Individual Features:

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

• Oscillator Output (Pin #9) at 77.76 MHz.

• Reference Output (Pin #1) at 19.44 MHz.

The SCG2020 accepts a 19.44 MHz Input

Reference (Pin #8) and provides a 19.44

MHz Output Reference (Pin #1) and a

77.76 MHz signal output on Output #2.

The LOL alarm is designed to tolerate 1

µs

p-p of jitter on the reference. Jitter greater

than 1

µs p-p will result in LOL alarm

pulses.
