Pendulum DA-36 Compact Point-to-Point Distribution Amplifier for reference frequency signals
The Distribution Amplifier DA-36 solves the problem of distributing a reference frequency from a central frequency standard to one or several receiving points.

It offers frequency distribution via optical fiber, or coax cable, with minimal jitter and is designed for reference signals of 10 MHz (sine). The distribution is completely analog, without the use of PLLs or other types of frequency recovery circuits that may introduce jitter or wander. The signal is filtered in a narrow-band, high-Q filter, which heavily suppresses noise and distortion.

DA-36 is a compact all-in-one transceiver module with 1 coax and 1 fiber input, plus1 fiber and 4 coax outputs.

System Structure
The DA-36 is designed to work with any Pendulum Frequency Standard (GPS-12R, 6688/89, GPS-88/89), any Fluke Frequency standard (908/909, 910, 910R) and with any reference clock from Orolia/Spectracom. It will also work with all other brands that produce a sine wave reference with amplitude between 0.2 and 2 Vrms.
