General Description

The SCG3041 is a mixed signal phase locked loop

generating 155.52 MHz LVPECL outputs from an

intrinsically low jitter voltage controlled crystal oscillator.

The SCG3041 is phase locked to an external 19.44 MHz

reference input. The SCG3041 is ideal for applications

using multiplication to obtain higher SONET frequencies.

The package dimensions are 0.75" x 1.25" x .45" on

a 6 layer, designed impedence, FR4 board with

castellated pins. Parts are assembled using high

temperature solder to withstand surface mount reflow

processes. See Fig. 4 for the solder profile.
