High Power Differential Line Driver/Receiver Features General Description • Complete ADSL differential driver and receiver • 54VP-P output drive into 100Ω differential • 50VP-P output drive into 50Ω differential • Driver 2nd/3rd harmonics of -70dBc/-75dBc at 2VP-P into 100Ω • Low supply current - 12.5mA per drive amplifier and 5mA per receive amplifier • Standard surface-mount package The EL1502C is a complete transceiver solution for high speed data transmission over twisted pair wires. It contains two wideband, highvoltage drivers and two low-noise receive amplifiers. The EL1502C is ideally suited for both ADSL and HDSL2 applications, in which it can supply a 50VP-P signal into a 50Ω differential load while exhibiting very low distortion. The receive amplifiers also have very low distortion and low-noise for superior reception of small signals. Applications The device is supplied in a standard form factor, 20-pin SOIC package. The eight center package pins of the package are used as ground connections and heat spreaders, allowing for operation over the full --40°C to +85°C temperature range. Ordering Information Part No Package 20-Lead SO Tape & Reel The line drivers of the EL1502C are current-feedback type amplifiers, which achieve a high slew rate while consuming moderate power. They retain their frequency response over a wide range of externally set gains. The receive amplifiers are of the voltage-feedback type and can be used to implement a hybrid coupler or filter functions using external passive components. The EL1502C operates on ±5V to ±15V supplies. It retains its bandwidth and linearity over the complete supply range. • ADSL line driver • HDSL2 line driver • Video distribution amplifier EL1502CM Outline # MDP0027 Connection Diagrams VIN-D1 1 20 VIN-D2 VOUTD1 2 19 VOUTD2 18 VS+ + + VS- 3 GND* 4 17 GND* GND* 5 16 GND* GND* 6 15 GND* GND* 7 14 GND* VOUT+R1 9 VIN-R1 10 13 VIN+D2 + - + - 12 VOUT+R2 11 VIN-R2 20-Pin Wide Body SOIC * Gnd pins are heat spreaders Note: All information contained in this data sheet has been carefully checked and is believed to be accurate as of the date of publication; however, this data sheet cannot be a “controlled document”.
