FUNCTIONAL DESCRIPTION
Principal synthesizer
Programmable reference and main dividers drive the
principal PLL phase detector. Two charge pumps produce
phase error current pulses for integration in an external
loop filter. A hardwired power-down input POFF (pin 9)
ensures that the dividers and phase comparator circuits
can be disabled.
The PRI input (pin 6) drives a preamplifier to provide the
clock to the first divider stage. The preamplifier has a high
input impedance, dominated by pin and pad capacitance.
The circuit operates with signal levels from 60 to 400 mV
(RMS), and at frequencies up to 2 GHz. The high
frequency divider circuits use bipolar transistors, slower
bits are CMOS. Divider ratios (512 to 131071) allow up to
2 MHz phase comparison frequency.
