Description

The PRL-240A is a self-contained high-speed TTL frequency divider capable of operating at clock frequencies in excess of 100 MHz. The PRL-240A has ÷2 and ÷10 outputs. The input resistance can be set to 500 Ω or 50 Ω by a toggle switch. A functional block diagram is shown in Fig.1.

The back-matched 50 Ω outputs can drive long lines and deliver greater than 2.2 V into 50 Ω loads.

The ÷2 output is a square wave, and the ÷10 output has an output pulse positive duty cycle of 40%. The square wave is useful for testing High and Low pass filters. The divider outputs are useful as 'scope triggers for viewing multi-frequency signals. The ÷2 signal is often needed as a control signal for split-cycle timing applications.

Each unit is housed in an attractive 1.3 x 2.9 x 2.9-in. extruded aluminum enclosure and has BNC I/O connectors. A ±8.5 V AC/DC Adapter is supplied with each unit.
