EL5178, EL5378

700MHz Differential Twisted-Pair Drivers

The EL5178 and EL5378 are single and triple high

bandwidth amplifiers with an output in differential form. They

are primarily targeted for applications such as driving

twisted-pair lines in component video applications. The

inputs can be in either single-ended or differential form but

the outputs are always in differential form.

On the EL5178 and EL5378, two feedback inputs provide

the user with the ability to set the gain of each device (stable

at minimum gain of 2).

The output common mode level for each channel is set by

the associated REF pin, which have a -3dB bandwidth of

over 110MHz. Generally, these pins are grounded but can be

tied to any voltage reference.

All outputs are short circuit protected to withstand temporary

overload condition.

The EL5178 is available in 8 Ld MSOP and SOIC packages

and EL5378 is available in a 28 Ld QSOP package. All are

specified for operation over the full -40°C to +85°C

temperature range.
