Description

The ADRF6510 operates from a 4.75 V to 5.25 V supply and consumes a maximum supply current of 258 mA when programmed to the highest bandwidth setting. When disabled, it consumes 2 mA. The ADRF6510 is fabricated in an advanced silicon-germanium BiCMOS process and is available in a 32-lead, exposed paddle LFCSP. Performance is specified over the -40°C to +85°C temperature range. The variable gain amplifiers that follow the filters provide 50 dB of continuous gain control with a slope of 30 mV/dB. The output buffers provide a differential output impedance of 20 that is capable of driving 1.5 V p-p into 1 k loads. The output commonmode voltage defaults to VPS/2, but it can be programmed via the VOCM pin. The built-in dc offset correction loop can be disabled if dc-coupled operation is desired. The high-pass corner frequency is defined by external capacitors on the OFS1 and OFS2 pins. The ADRF6510 is a matched pair of fully differential low noise and low distortion programmable filters and variable gain amplifiers (VGAs). Each channel is capable of rejecting large out-ofband interferers while reliably boosting the wanted signal, thus reducing the bandwidth and resolution requirements on the analog-to-digital converters (ADCs). The excellent matching between channels and their high spurious-free dynamic range over all gain and bandwidth settings make the ADRF6510 ideal for quadrature-based (IQ)communication systems with dense constellations, multiple carriers, and nearby interferers. The filters provide a six-pole Butterworth response with 0.5 dB corner frequencies programmable through the SPI port from 1 MHz to 30 MHz in 1 MHz steps. The preamplifier that precedes the filters offers a pin-programmable option of either 6 dB or 12 dB of gain. The preamplifier sets a differential input impedance of 400 and has a common-mode voltage that defaults to 2.1 V but can be driven from 1.5 V to 2.5 V.

The features of ADRF6510 can be summarized as (1)matched pair of programmable filters and VGAs; (2)continuous gain control range: -5 dB to +45 dB; (3)6-pole filter 1 MHz to 30 MHz in 1 MHz steps, 0.5 dB corner frequency/ SPI programmable; (4)6 dB front-end gain step; (5)IMD3: >55 dBc for 1.5 V p-p composite output; (6)HD2, HD3: >60 dBc for 1.5 V p-p output; (7)differential input and output; (8)adjustable output common-mode voltage; (9)optional dc output offset correction; (10)power-down feature; (11)single 5 V supply operation.

The absolute maximum ratings of ADRF6510 are (1)supply voltage:s, VPS, VPSD: 5.25 V; (2)ENBL, GNSW, OFDS, LE, CLK, DATA, SDO: VPS + 0.6 V; (3)INP1, INM1, INP2, INM2: VPS + 0.6 V, GND - 0.6 V; (4)OPP1, OPM1, OPP2, OPM2: VPS + 0.6 V; (5)OFS1, OFS2: VPS + 0.6 V; (6)GAIN: VPS + 0.6 V; (7)internal power dissipation: 1.4 W; (8) JA (exposed pad soldered to board): 37.4°C/W; (9)maximum junction temperature: 150°C; (10)operating temperature range: -40°C to +85°C; (11)storage temperature range: -65°C to +150°C; (12)lead temperature (Soldering 60 sec)300°C.
