Description
The ZL30462 is a Timing Module, which functions as a
complete system clock solution for general timing
applications.
The ZL30462 has been designed around Zarlink's
Digital and Analog Phase Locked Loop (DPLL and
APLL) technology and can lock to one of two inputs
that can be derived from two independent sources.
The inputs automatically detect if one of four
frequencies is present, 8 kHz, 1.544 MHz, 2.048 MHz
or 19.44 MHz. The module has three jitter attenuated
output clocks one 19.44 MHz (CMOS) and two
155.52 MHz (LVPECL). In addition to these outputs the
module also supplies an 8 kHz frame pulse plus
2.048 MHz, 8.192 MHz and 16.384 MHz clocks.
