TTL Freq. Divider (f/2, f/4, f/8, f/16)

Features: 100 MHz Toggle Frequency 50 Ω Outputs deliver > 2.2 V into 50 Ω loads TTL/CMOS Compatible Input Levels 50 Ω or 500 Ω Input Resistance BNC I/O Connectors Ready-to-Use 1.3 x 2.9 x 2.9-in. Module includes AC/DC Adapter Applicatios: Count down signal for 'scope trigger Control Signal for split cycle timing Counter Output simulation Square Wave Generator An Essential Lab Tool for Working with TTL/CMOS Circuits Download Datasheet Description The PRL-220A is a self-contained high-speed TTL frequency divider capable of operating at clock frequencies in excess of 100 MHz. The PRL-220A has ÷2, ÷4, ÷8 and ÷16 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 outputs are square waves, useful for testing High and Low pass filters. The divider outputs are useful as 'scope triggers for viewing mu
