Applications: TTL/CMOS Clock Distribution 2 x 1:10 Fanout Line Driver High Speed Digital Communications System Testing 1 PPS Distribution/IRIG-B Distribution Mini Modular Instrument Features: fMAX > 100 MHz Drives 100 ft of cable @ 80 MHz 1.8 ns Typical Output Rise & Fall Times 2.5 V into 50 Ω Typical TTL Compatible 50 Ω or 10 kΩ Input 20 in-phase 50 Ω TTL Outputs (two sets of 10) Active Low EN (Enable) Input BNC I/O Connectors DC Coupled I/Os Self-contained 3.0 x 6.8 x 4.0-in. unit includes an AC/DC Adapter Description The PRL-4220 is a 2 x 1:10 fanout 50 Ω TTL Line Driver. It is intended for distribution of two independent high-speed clock and logic signals (e.g. CLK and DATA) to multiple loads via long lines. The 50 Ω back-terminated outputs can drive long lines with or without 50 Ω load terminations. With 50 Ω load terminations, however, all outputs of the PRL-4220 can drive 100 ft of 50 Ω cables at clock rates greater than 80 MHz. The PRL-4220 is implemented
