SP5070F
The SP5070 is a single modulus frequency synthesiser
for use in Satellite TV receivers and together with an
appropriate voltage controlled oscillator (VCO), forms a
complete phase locked loop (PLL) synthesiser. The circuit
consists of a prescaler with preamplifier and a fixed modulus
divider. The phase comparator is fed with a reference
frequency derived from an external oscillator or crystal. The
comparator has a charge pump output amplifier stage
around which feedback may be applied. Only an external
transistor is required for varicap line driving.
