General Description

Features

The SCG2500 is a mixed-signal phase lock loop

generating CMOS outputs from an intrinsically low jitter

voltage controlled crystal oscillator.

The SCG2500 can lock to one of two possible input

reference frequencies at 8 kHz which is selectable

using one input select pin.

• Phase Locked Output

Frequency Control

• Intrinsically Low Jitter Crystal

Oscillator

• Two Selectable References @ 8

kHz

Further features include an alarm output to indicate

Loss of Reference, LOR, or Loss of Lock, LOL. If only

one of the references is lost, the unit will disable its

phase detector and will signal an alarm, but will not

switch reference automatically. If both references are

lost, the SCG2500 will enter a Free Run state which will

guarantee a 20 ppm accurate output. Additionally, the

Free Run mode may be entered manually by applying a

high signal to the Free Run pin. If the unit is in Free

Run mode, the Free Run status pin will be high.

The outputs may be put into the tri-state high

impedance condition for external testing purposes by

applying a high signal to the Reset/Tri-State pin.

The filtered 8 kHz is derived from the oscillator

output. The offset between the filtered output and the

reference input will change with each reference

rearrangement.

• Alarm Output

• Tri-Statable Oscillator and Alarm

Outputs

• Force Free Run Function

• Automatic Free Run Operation

upon loss of both references

• Input Duty Cycle Tolerant

• 3.3 Volt Power Supply

• Small Size: 0.775 x 0.825 inches

• Surface Mount, DIL Package

The package dimensions are .775” x .8” x .35” on a

six layer FR4 board with surface mount pins. Parts are

assembled using high temperature solder to withstand

surface mount reflow process.
