Fully integrated alignment-free low phase noise local oscillator Selectable RF Bypass I2C patible control 3.3 Volt Supply 28 pin 5x5 mm QFN Package -10 ° C to +85 ° C Description The ZL10037 is a fully integrated direct conversion tuner for digital satellite receiver systems. It provides excellent immunity to posite undesired channels. The device also contains a RF Bypass for connecting to a second receiver module. The ZL10037 is simple to use, requiring no alignment or tuning algorithms and uses a minimum number of external ponents. The device is programmable via a I2C patible bus. A plete reference design (ZLE10542) is available using ZL10313 demodulator.
