Description

The PRL-425RS is a dual channel, universal input differential receiver with RS-422 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-425RS has differential RS-422 outputs for driving floating 124 Ω loads, typically the configuration used for RS-422 receivers. 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-425RSTR have Triax input connectors instead of SMA input connectors. Model PRL-425RSTR-C002 has SMA input connectors and Triax output connectors, and is available by special order.

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

Notes:

All PRL products with Triax connectors use Trompeter P/N CBBJR79, Right Angle Circuit Board Bulkhead Jack, 3-lug (Numbered page 10, document page 11 of 142). Any Trompeter 70-series Triax Cable Plug with 3 lugs (e.g. PL75-9, 3-lug) will mate with CBBJR79.

While we believe these models to be accurate, no representations are made as to accuracy or suitability for any application:
