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.
