3 / 9 page 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 ORDERING INFORMATION SL1454 NA DP (14-lead plastic DIL package) SL1454 WIDEBAND LINEAR FM DETECTOR FOR SATELLITE TV 2039-2·1 DP8 0V DEMODULATOR COIL DEMODULATOR COIL 0V INPUT SIGNAL INPUT REF VCC VIDEO OUTPUT 1 2 3 4 8 7 6 5 SL1454 Fig. 1 Pin connections - top view ABSOLUTE MAXIMUM RATINGS Operating temperature range Supply voltage, pin 6 Input voltage, pin 7 or 8 Storage temperature Junction temperature 2 10 °C to180°C 7V 2·5V p-p 2 55 °C to 1150°C 1 175 °C Fig. 2 Block diagram DEMODULATOR INPUT REF 8 7 INPUT SIGNAL INPUT AMPLIFIER 3 2 QUADRATURE DEMODULATOR COMPONENTS VIDEO AMPLIFIER 5 VIDEO OUTPUT 6 VCC 1 0V 4 0V 1k 1k 2k 2k 70p 2p 2p ADVANCE INFORMATION |
