Description:
The TSA5527T 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
