The NBC12429 and NBC12429A are general purpose,
Phase-
-Lock-
-Loop (PLL) based synthesized clock sources. The VCO
will operate over a frequency range of 200 MHz to 400 MHz. The
VCO frequency is sent to the N-
-output divider, where it can be
configured to provide division ratios of 1, 2, 4, or 8. The VCO and
output frequency can be programmed using the parallel or serial
interfaces to the configuration logic. Output frequency steps of
125 kHz, 250 kHz, 500 kHz, or 1.0 MHz can be achieved using a
16 MHz crystal, depending on the output dividers. The PLL loop filter
is fully integrated and does not require any external components.
