DPS7040 VLSI RF Tuner for Terrestrial and Cable TV Applications www.DataSheet4U.com OVERVIEW The DPS7040 is a highly versatile, high performance, single-chip RF tuner integrated circuit (IC). It is capable of receiving input signals in the TV band (48~870 MHz) and translating them down to an intermediate frequency in the 30 to 60 MHz range. This VLSI product integrates all the essential components of an RF receiver, including the LNA, RFAGC, mixers, filters, oscillators, PLL’s, and IF variable gain amplifier, thereby requiring minimal external components and eliminating manual tuning. This high level of on-chip functionality translates to a reduction in the overall bill of materials, assembly, alignment and test costs. The high level of integration provides a dramatic reduction in the footprint occupied by the RF tuner, thereby enabling multi-tuner/multi-stream systems in small form-factor. The DPS7040 features a proprietary receiver architecture, which eliminates the need for an external 1st IF filter. The IC is specifically designed to meet the rigorous distortion demands of the CATV environment, at the same time having excellent sensitivity for terrestrial applications, while drawing minimal supply current. The IC is programable via a standard 2 wire interface. To enable multtuner architectures the Slave address may be programmed via an external resistor. The synthesizer and oscillator sections have been designed to exhibit extremely good close-in phase noise, making the DPS7040 the ideal choice where there is a requirement to support digital TV standards. The DPS7040 directly supports many common digital TV, analog TV and data standards, with appropriate choice of demodulator. Due to the inclusion of the IF variable gain amplifier, the output of the DPS7040 can be directly connected to the input of most demodulators with no external active components.
