UNISONIC TECHNOLOGIES CO., LTD
LINEAR INTEGRATED CIRCUIT
WIDEBAND PLL FM DEMODULATOR
- DESCRIPTION
As a wideband PLL FM demodulator, the UTC L2572 is intended for application in satellite tuners primarily.
The device includes all the necessary elements, with external oscillator sustaining network and the exception of loop feedback ponents, to form a PLL system operating at frequencies up to 800MHz pletely.
An AFC with window adjust (whose output signal can be used to correct for any frequency drift at the head end local oscillator) is provided.
- Features
- Constant voltage and constant current control
- Single chip PLL system for wideband FM demodulation
- Simple low...
