Cable pre-processor and low-power silicon tuner

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.
