General Description

Features

The SCG4603AG5 is a digital phase locked loop

generating CML outputs from an intrinsically low

jitter voltage controlled crystal oscillator.

The SCG4603AG5 can lock to one of two

external 8 kHz references, which is selectable

using the SELAB input select pin. The unit is

tolerant of different reference duty cycles.

The SCG4603AG5 includes an alarm output

that indicates deviations from normal operation. If a

Loss-of-Reference (LOR) or Loss-of-Lock (LOL) is

detected the alarm with indicate the need for a

reference rearrangement. If both references A and

B are absent the module will enter Free Run

operation. The FRstatus pin will indicate that the

module is in Free Run operation. Frequency

stability during Free Run operation is guaranteed to

±20 PPM. Additionally the Free Run mode may be

entered manually.
