The PRL-414B is a 1:4 fanout 50Ω TTL Line Driver. It is intended for distribution of high-speed clock and logic signals to multiple loads via long lines. The 50Ω back-terminated outputs can drive long lines with or without 50 Ω load terminations.
With 50Ω load terminations, however, all outputs of the PRL-414B can drive 100ft of 50Ω cables at clock rates greater than 80MHz.
In one important application, the PRL-414B is used for distributing a precision clock signal to a number of test stations in the lab.
The input resistance of the PRL-414B can be selected to be either 50Ω or 1kΩ by a switch.
The 1kΩ-input is desirable when interfacing with low power circuits. All I/O’s are DC coupled and have BNC connectors.
The PRL-414B is housed in a 1.3 x 2.9 x 2.9-in. extruded aluminum enclosure and is supplied with a ±8.5V (± 1A) AC/DC Adapter.
