PULSE DISTRIBUTION AMPLIFIER, PD-5

FEATURES

 1 input, 5 outputs

 10 ns propagation delay

 50 ohm output: 2 Vp-p

 Low temperature coefficient: 3 ps/ºC

 Matched channel delays

APPLICATIONS

 1 PPS distribution

 Reference clock distribution

 Time synchronization

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 0.5 ns. The small propagation delay characteristics and low

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

requirements are 100-240 VAC and an optional +24 VDC.
