Description
The ZL10037 is a fully integrated direct conversion
tuner for digital satellite receiver systems. It provides
excellent immunity to composite 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 components. The device is programmable via
a I
2
C compatible bus.
A complete reference design (ZLE10542) is available
using ZL10313 demodulator.
