PD OPTIONS

PD-5,

This amplifier model takes one input and provides five outputs. This model is available in a 2U high,

half rack mount enclosure, 3.5” X 8.4” X 12”.

PD-5RM-B, This amplifier model takes one input and provides five outputs. This model is available in a

1U high, 19” full rack mount enclosure.

PD-10RM-B, This amplifier model takes one input and provides ten outputs. This model is available in a

1U high, 19” full rack mount enclosure. A battery back up module for uninterrupted operation may be ordered

as an option.

DESCRIPTION

The PD-5 is a TTL pulse distribution amplifier. The outputs are designed to drive low impedance loads and

long 50 or 75 Ω cables. The propagation delay through the amplifier is typically 10 ns. The channel-to-

channel delay differences are less than 1 ns. The small propagation delay characteristics and low

temperature coefficient of delay are essential for the distribution of high quality timing signals. The unit

operates on 110/220 VAC.
