EL5173, EL5373

450MHz Differential Twisted-Pair Drivers

The EL5173 and EL5373 are single and triple high

bandwidth amplifiers with a fixed gain of 2. 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.

The output common mode level for each channel is set by

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

over 190MHz. 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 EL5173 and EL5373 are specified for operation over the

full -40°C to +85°C temperature range.

Features

• Fully differential inputs and outputs

• Differential input range ±2.3V

• 450MHz 3dB bandwidth at fixed gain of 2

• 900V/µs slew rate (EL5173)

• 1100V/µs slew rate (EL5373)

• Single 5V or dual ±5V supplies

• 40mA maximum output current

• Low power - 12mA per channel

• Pb-free plus anneal available (RoHS compliant)

Applications

• Twisted-pair drivers

• Differential line drivers

• VGA over twisted-pairs

• ADSL/HDSL drivers

• Single ended to differential amplification

• Transmission of analog signals in a noisy environment
