DESCRIPTION

The PRL-432N and PRL-433N are a pair of dual channel NECL Interface Translators designed specifically for use with high speed recording

instruments in satellite image transmission applications. The PRL-432N is the Recorder Playback Translator, and the PRL-433N is the Recorder

Record Translator. They are especially suited for interfacing with the SONY DFC-1800 Variable Rate Buffer used in the DIR-1000 recording

system.

The inputs of the PRL-432N consist of two triax connectors, each internally terminated with 124 Ω between the pin and the ring. They are

designed to interface with the 124 Ω differential Serial

The improved design of the “N” version of the PRL-432N, however, enables the differential 124 Ω input to cover a CMR between -2.5 V and

+4 V. Within this CMR, the PRL-432N inputs are compatible with NECL, PECL, LVPECL, RS422 or LVDS differential 124 Ω output drive

circuits. The complementary NECL outputs have SMA connectors and are designed for driving 50 Ω loads terminated to -2 V or AC-coupled 50 Ω

loads.

The differential inputs of the PRL-433N have SMA connectors. A switch selects either single-ended or differential inputs. In the differential input

mode, both inputs D and

well. In the single input mode, signals should be connected to the D inputs only. The

and termination resistors

are designed to interface with the 124 Ω differential Serial

resistors enable these outputs to drive differential 75 Ω loads as well.

The PRL-432N and PRL-433N are each housed in an attractive 1.3 x 2.9 x 3.9-in. extruded aluminum enclosure and supplied with a ±8.5 V

AC/DC Adapter. If mounting is desired, a pair of 35001420 mounting brackets can accommodate two PRL modules of the same length. A number

of PRL modules can also share a single ±8.5 V AC/DC adapter using the PRL-730 or PRL-736 voltage distribution module. Please see our

Accessories page for further details.
