Freescale Semiconductor’s MC44S803 is
a 3.3V, low-power, high-performance,
single-chip CMOS broadband tuner. This chip
offers a cost-effective, low-power solution for
the high-performance analog and digital TV
market. The highly integrated third generation
silicon tuner receives 48 MHz to 861 MHz radio
frequency (RF) signals and converts them to a
second intermediate frequency (IF) of 30 MHz
to 50 MHz.
The single-chip broadband tuner uses
double-conversion architecture, which
eliminates tracking filters and their manually
aligned coils. Two IF outputs are provided to
support systems with multiple demodulators
(e.g. one digital demodulator and one analog
TV demodulator).
The MC44S803 is designed to meet all Data
Over Cable Service Interface Specifications
(DOCSISs) for 64- and 256-quadrature
amplitude modulation (QAM) as well as the
NorDig Unified 1.0.1 specifications for coded
orthogonal frequency-division multiplexing
(COFDM) for DVB-T.
The device is available in a Pb-free 64-pin quad
leadless package (QFN). The chip is carefully
designed for flexible power consumption and
dissipates as low as 700 mW typical.
