TSA5527T Datasheet PDF – PLL Frequency Synthesizer

Part Number : TSA5527T

Function : 1.3 GHz universal bus-controlled TV synthesizer

Package : SO, SSOP 16 Pin Type

Manufacturers : Philips Electronics

Pinouts :

TSA5527T datasheet

Description :

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.

Features

1. Complete 1.3 GHz single chip system
2. Four PNP band switch buffers (40 mA)
3. 33 V output tuning voltage
4. In-lock detector
5. 5-step ADC
6. 15-bit programmable divider
7. Low power and low radiation

Block Diagram

Applications

1. TV tuners and front ends
2. VCR tuners.
