SL1452
WIDEBAND LINEAR FM DETECTOR FOR SATELLITE TV
With a minimum of external components, the SL1452 forms a
complete wideband FM detector suitable for use in satellite TV.
The video output and bandwidth may be optimised by adjustment
of the working Q of the quadrature coil.
FEATURES
s High Operating Frequency Simplifies Image Filtering
s Negligible Differential Gain and Phase Errors
s Video Bandwidth Suitable for High Definition TV
s High Sensitivity and Wide Dynamic Range
s Wide Operating Frequency Range: 300 to 1000 MHz
s Electrostatic Protection*
* Normal ESD handling precautions should be observed
