Dual Channel Differential DSL Line Driver for Globespan CO Chipsets

The EL1529 is to be used with Globespan's G7566-850 CO chipset for high performance long reach and high speed applications, including ADSL2, ADSL2+, G.Span, and G.Span+.

The EL1529 is an integral part of the signal chain. The driver has been optimized for flat gain response and reduced harmonic distortion and noise in the bands of interest to improve the overall signal to noise in the system.

These drivers achieve a total harmonic distortion (THD) measurement of typically -70dB @ 1.1MHz, while consuming typically 5mA per DSL channel of total supply current. This supply current can be set using a resistor on the I adjust supply current to one of four pre-set modes (full-I 3/4-I

pin. Two other pins (C0 & C1) can also be used to

ADJ

, 1/2-IS, and full power-down). The EL1529 operates

on ±5V to ±12V supplies and retains its bandwidth and linearity over the complete supply range.

The device is supplied in the small footprint (4x5mm) 24-pin QFN package and is specified for operation over the full

-40°C to +85°C temperature range.
