Description
The ZL10036 is a single chip wideband direct
conversion tuner, with integral RF bypass, optimized
for application in digital satellite receiver systems.
The device offers a highly integrated solution to a
satellite tuner function, incorporating an I²C bus
interface controller, a low phase noise PLL frequency
synthesizer, a quadrature phase split tuner, a fully
integrated local oscillator which requires no production
set up, and adjustable baseband channel filters.
The I²C bus interface controls all of the tuner
functionality including the PLL frequency synthesizer,
the bypass disable and the baseband gain and
bandwidth adjust.
