General Description

Features

The SCG2503 is a mixed-signal phase lock loop

generating CMOS outputs from an intrinsically low jitter

voltage controlled crystal oscillator.

The SCG2503 can lock to one of two possible input

reference frequencies at 8 kHz which is selectable using

one input select pin.

• 26Hz Minimum Jitter Bandwidth

• Phase Locked Output

Frequency Control

• Intrinsically Low Jitter Crystal

Oscillator

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 SCG2503 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 Force Free Run pin. If the unit is in

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

All outputs, except the Oscillator Output, 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.

• Two Selectable References @ 8

kHz

• Alarm Output

• Tri-Statable Alarm Outputs and

Reference Output

• Force Free Run Function

• Automatic Free Run Operation

upon loss of both references

• Input Duty Cycle Tolerant

• 3.3 Volt Power Supply

• Small Size: 0.78” x 0.83” x 0.35”

maximum

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.

• Surface Mount, DIL Package

The package maximum dimensions are .780” x .830”

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.
