| EL1502C - Product Brief EL1502C - Product Brief High Power Differential Line Driver/Receiver Features * Complete ADSL differential driver and receiver * 54VP-P output drive into 100 differential * 50VP-P output drive into 50 differential * Driver 2nd/3rd harmonics of -70dBc/-75dBc at 2VP-P into 100 * Low supply current - 12.5mA per drive amplifier and 5mA per receive amplifier * Standard surface-mount package General Description 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 50 differential load while exhibiting very low distortion. The receive amplifiers also have very low distortion and low-noise for superior reception of small signals. 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. 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 --40C to +85C temperature range.
