450MHz Differential Twisted-Pair Drivers
Features
• Fully differential inputs and outputs
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.
• Differential input range ±2.3V
• 450MHz 3dB bandwidth at fixed gain of 2
• 900V/µs slew rate (EL5173)
• 1100V/µs slew rate (EL5373)
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.
• Single 5V or dual ±5V supplies
• 40mA maximum output current
• Low power - 12mA per channel
• Pb-free plus anneal available (RoHS compliant)
All outputs are short circuit protected to withstand temporary
overload condition.
Applications
• Twisted-pair drivers
The EL5173 and EL5373 are specified for operation over the
full -40°C to +85°C temperature range.
• Differential line drivers
