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 50V
signal into a 50Ω differential load while exhibiting
P-P
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 --
-40°C to +85°C temperature range.
