SCG4521 General Description

The SCG4521 is a mixed-signal phase locked loop generating LVPECL outputs from an intrinsically low jitter, voltage controlled, crystal oscillator. The LVPECL outputs may be disabled. The SCG4521 can lock to one of two external references, which is selectable using the SELAB input select pin. The un.
