Description

The PRL-425N is a dual channel, universal input, differential receivers with NECL outputs. The floating 100 Ω inputs are designed for interfacing with differential signals within the common mode range of -2.4 V to +4.0 V. Therefore, they are compatible with LVDS, RS422, LVPECL, LVTTL/CMOS, NECL, PECL or TTL differential input signals. The PRL-425N has complementary NECL outputs for driving 50 Ω loads terminated to -2 V, floating 100 Ω loads or AC-coupled 50 Ω loads. It is also a long line driver, designed specifically for use with high speed data communications applications. Functional block diagrams of these devices are shown in Fig. 1 and Fig. 2. Model numbers with suffix TR, such as PRL-425NTR, have Triax input connectors instead of SMA input connectors.

The PRL-425N is housed in a 1.3 x 2.9 x 3.9-in. extruded aluminum enclosure, and each is provided with a ±8.5 V AC/DC Adapter. Optional mounting brackets are available.
