Description

The PRL-173 is a ready-to-use TTL crystal clock source module with 50 Ω back terminated outputs, designed for driving long lines with or without 50 Ω terminations.

The PRL-173 converts the internal crystal clock frequency f into 2-Φ clock outputs of f and f/5.

The maximum frequency output of the PRL-173 is 50 MHz, model number PRL-173-50. Standard crystal frequencies provided are 1 MHz, 2.5 MHz, 5 MHz, 10 MHz, 25 MHz and 50 MHz. Other crystal frequencies are also available by special order, with a 3-digit suffix indicating the requested frequency of the un-divided "f" output.

Each clock source module is housed in a 1.3 x 2.9 x 2.9-in. extruded aluminum enclosure and is supplied with a ±8.5V 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 ±8.5V AC/DC adapter using the PRL-730 voltage distribution module. Please see the Accessories Section for more detail.
