SL1454
WIDEBAND LINEAR FM DETECTOR FOR SATELLITE TV
The SL1454 is a wideband FM demodulator designed to
operate with a carrier frequency between 70MHz and 150MHz.
The internal circuitry of the device is similar to that of the SL1452
except that the quadrature demodulator operates at the input
frequency.
FEATURES
s Excellent Threshold
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: 70 to 150MHz
