Description
The Le87251 is a dual channel differential amplifier
designed to drive full rate ADSL2+ signals with very
low power dissipation. The Le87251 contains two pairs
of wide band amplifiers designed with Zarlink’s HV30
Bipolar SOI process for low power consumption in
DSL systems. The amplifiers have an internal fixed
gain, which helps to eliminate external feedback and
gain setting resistors.
The drivers achieve better than -75 dB THD while
driving a 1MHz, 16Vp_p signal into a 60? load. The
amplifiers are enabled by forcing the ENAB/ENCD
pins to ground. Leaving the ENAB/ENCD pins floating
or forcing them high will disable the two amplifiers. The
ENAB and ENCD pins are pulled up to an internal 2.5V
through on-chip 50k? resistors.
Le87251 device is one of the most cost-effective and
high performance line drivers for xDSL2+ applications.
