描述 Description

TDA18204HN is a cable pre-processor coupled with a low-power silicon tuner to addressthe front-end part of cable modems and gateways.
The cable pre-processor allows for smooth signal processing by a wideband receiverconnected to its output. It inputs single ended cable signal and provides amplification, tiltcompensation in the 42 MHz to 1 GHz bandwidth, low-pass filtering to reject signalsabove 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 poweras 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® FullSpectrum Transceiver (FST) product family to make the full multi-stream RF front end of acable receiver or cable modem in a very small form factor, while providing with noadditional component the low-power path for VoIP in battery operated mode.

特性 Features

• RF front end for FST family of products
• Very low-Noise Figure (NF); 3.9 dB typical
• Very low-power consumption; 360 mW in wideband application
• Direct interfacing to the cable with single ended input
• Covers all cable standards worldwide
• Input frequency range up to 1 GHz
• Gain control to provide a stable output power irrespective of the input power
• Cable tilt correction to provide a flat output spectrum whatever the distance from thecable head-end to the user
• Balanced output to drive directly a high-performance ADC like the one implemented inNXP® FST products
• Narrowband low-power silicon tuner
• Additional outputs for optional standalone tuners or Loop-Through (LT)
