The Pendulum DA-36 frequency Distribution Amplier offers an economical solution to the
problem of low-jitter transfer of frequency reference signals over longer distance. Whether
the need is to distribute between remote buildings, oors or rooms, or whether the need is
a big point-to-multipoint system with thousand of receivers, or just one single point-to-point
distribution, DA-36 will do the job.

.

It offers frequency distribution via optical ber, 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 reconstructed with the help of a narrowband, high-Q lter, which heavily suppresses noise and distortion.

receiving element, which totally eliminates ground current loops
- a common problem with coax distribution systems. The ber is
insensitive to crosstalk and ESD, and will not pick up any noise or
inteference like long-line coax cables do. Optical bers are easy
to install, with their small diameter and highly exible structure,
compared to expensive, bulky and stiff low-loss coax cables.

The Distribution Amplier DA-36 solves the problem of distributing
a reference frequency from a central frequency standard to one or
several receiving points.
