DESCRIPTION

The DRV1101 is fixed gain differential line driver
designed for very low distortion operation when driv­ing DSL line transformers. It is designed for use as the
upstream line driver for ADSL G.Lite, and as both
upstream and downstream line drivers in CAP sys­tems. Operating on a single 5V supply, the DRV1101
can supply up to 230mA peak output current. The
output voltage can swing up to 9.5Vp-p on a single 5V
supply. In ADSL G.Lite applications, DRV1101 can
supply up to 10dBm average line power with a crest
factor of 5.3 for a peak line power delivered of
approximately 25dBm. It is packaged in a 8-lead
SOIC.

FEATURES

● HIGH OUTPUT CURRENT: 230mA

● VERY LOW THD AT HIGH POWER:

–81dBc at 6Vp-p, 100kHz, 100Ω

● FIXED DIFFERENTIAL GAIN: 3V/V

APPLICATIONS

● DSL TWISTED PAIR LINE DRIVER

● COMMUNICATIONS LINE DRIVER

● TWISTED-PAIR CABLE DRIVER

NOTES: (1) Measurement Bandwidth = 500kHz. (2) Time from 50% point of input step to 50% point of output step. (3) For step input. (4) Output common-mode voltage
follows input common-mode voltage; therefore, if input V

CM

= VDD/2, then output VCM = VDD/2. (5) THD = 1%.

SPECIFICATIONS

Typical at 25°C, VCM = VDD/2, VDD = +5.0V, unless otherwise specified.
