TDA18204HN is a cable pre-processor coupled with a low-power silicon tuner to address
the front-end part of cable modems and gateways.
The cable pre-processor allows for smooth signal processing by a wideband receiver
connected to its output. It inputs single ended cable signal and provides amplification, tilt
compensation in the 42 MHz to 1 GHz bandwidth, low-pass filtering to reject signals
above 1 GHz and provides a balanced output signal.
The low-power silicon tuner can be used for the battery-powered “emergency call”
function of the Cable gateways. It provides a single channel reception using as small power
as possible. The output signal of the low-power silicon tuner section is a low-IF signal,
interfacing a narrowband ADC at system level.
TDA18204HN copes with all cable standards worldwide and interfaces ideally to NXP® Full
Spectrum Transceiver (FST) product family to make the full multi-stream RF front end of a
cable receiver or cable modem in a very small form factor, while providing with no
additional component the low-power path for VoIP in battery operated mode.
