Applications: TTL/CMOS Clock Distribution 1:22 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 1 kΩ Input Twenty in-phase 50 Ω TTL Outputs Two auxiliary 50 Ω TTL Outputs suitable for cascading Active Low EN (Enable) Inputs for each bank of 10 outputs BNC or SMA I/O Connectors, plus two SMA auxiliary outputs DC Coupled I/Os Self-contained 3.0 x 6.8 x 4.0-in. unit includes an AC/DC Adapter Description The PRL-4122-BNC is a 1:22 fanout, 50 Ω TTL Line Driver. It is intended for distribution of high-speed clock and logic signals 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-4122 can drive 100 ft of 50 Ω c
