The EL1502 is a complete transceiver
solution for high speed data
transmission over twisted pair wires. It
contains two wideband, high-voltage drivers and two lownoise receive amplifiers. The EL1502 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 EL1502 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.
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
Applications
• ADSL line driver
• HDSL2 line driver
• Video distribution amplifier
