Overview
SP5070 2.
GHz Fixed Modulus Frequency Synthesiser DS3966-2.
2 May 996 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.
