Description
The ZL10039 is a fully integrated direct conversion tuner for digital satellite receiver systems, targeted primarily at free-to-air DVB-S receivers where high sensitivity is a priority. The device also contains a RF Bypass for connecting to a second receiver module. The ZL10039 is simple to use, requiring no alignment or tuning algorithms and uses a minimum number of external components. The device is programmable via a I2C compatible bus. A complete reference design (ZLE10541) is available using ZL10313 demodulator.
