Part Number : TSA5520
Function : 1.3 GHz universal bus-controlled TV synthesizer; 3-wire
Package : SSOP, SO 16 Pin
Manufacturers : Philips Electronics
The device is a single-chip PLL frequency synthesizer designed for TV and VCR tuning systems. The circuit consists of a divide-by-eight prescaler with its own preamplifier, a 15-bit programmable divider, a crystal oscillator and its programmable reference divider and a phase/frequency detector combined with a charge-pump which drives the tuning amplifier and the 33 V output. Four high-current PNP band switch buffers are provided for band switching. Two PNP buffers can be switched on simultaneously. The sum of the collector currents is limited to 50 mA.
