GENERAL DESCRIPTION:

The SCG304 is a digital phase locked loop generating 155.52 MHz LVPECL

outputs from an intrinsically low jitter voltage controlled crystal oscillator. The SCG304

is phase locked to an external 19.44 MHz reference input.

The unit has a fast acquisition time of about 1 second and it is tolerant of different

reference duty cycles. The SCG304 is ideal for applications using multiplication to

obtain higher SONET frequencies.

The package dimensions are 0.75” x 1.20” x .40” on a 4 layer FR4 board with

castellated pins. Parts are assembled using high temperature solder to withstand surface

mount reflow processes.
