| MITSUMI 2nd RF Units for BS Digital Broadcasting Receiver TSU37 Series DBS 2nd RF Units, CATV Converters OUTLINE This is an ultra-small second RF unit for BS digital broadcast/reception, incorporating a demodulation IC and capable of receiving BS digital, 110 degree CS and conventional CS. Because it is ultra-small with a single power supply, it can be used for a variety of purposes, such as thin receivers. FEATURES 1. Excellent BER characteristics even for 110 degree CS reception. (8PSK, 950 - 2150MHz) 2. Ultra-small size achieved through adoption of direct conversion IC in the RF section. (20cc) 3. Contains ISDB high-function and high-performance demodulation IC that supports ISDB-S. 4. High sensitivity (-80dBm, typ.) with good interference characteristics. 5. Excellent phase noise characteristics and high C/N margin. 6. Supports virtical/horizontal configuration. (Ideal for slim TVs, PC expansion slots, etc.) 7. Supply voltage driven by 3.3V single power supply.
