PRL-420TD Pulse Research Lab Dual Channel Differential TTL Line Driver

The Pulse Research Lab PRL-420TD Dual Channel Differential TTL Line Driver is a dual channel single-ended input, differential output TTL Line Driver. Each channel has a 50 Ω TTL/CMOS compatible input and a pair of differential 50 Ω outputs for driving long lines, in excess of 100 ft, with or without 50 Ω terminations. The input threshold voltage can be selected between 1.5 V and 1 V using a front panel switch. The 1 V threshold makes easy interfacing with 3.3V TTL/CMOS devices.

The PRL-420TD is intended for use in testing and interfacing of high speed digital communication circuits, where conversion from single-ended TTL/CMOS level signals to differential signals is often required. The differential outputs are ideal for driving RS422 input circuits and for high speed ADCs where a differential clock input is often required. The PRL-420TD complements other PRL-series Level Translators, such as the PRL-420ND/PD,PRL-450ND/PD and PRL-460NPD/PND in system integration applications where interconnections among different logic signals are often necessary.

The PRL-420TD is a ready-to-use functional module housed in a 1.3 x 2.9 x 3.9-in. extruded aluminum enclosure and is supplied with a ±8.5V AC/DC Adapter. BNC input and SMA output connectors are provided.
