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 I虜C 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 I虜C bus interface controls all of the tuner
functionality including the PLL frequency synthesizer,
the bypass disable and the baseband gain and
bandwidth adjust.
