DESCRIPTION
The CSDA-1 is a high performance clock signal distribution and isolation amplifier. The device is used to
provide distribution of 1 PPS signals, 5 MHz signals and 10 MHz signals. The CSDA-1 contains a pulse
distribution module with one input and five buffered outputs that can drive a 50-ohm cable. The second module
is a 5 MHz distribution amplifier with one input and five outputs. The third module provides five buffered and
isolated 10 MHz signals that are obtained by doubling the 5 MHz input signal. The channel-to-channel isolation
in the RF distribution modules is typically 125 dB and reverse isolation is typically greater than 135 dB. The
phase noise of the modules is exceptionally low, typically –150 dBc/Hz @ Fourier frequency of 1 Hz and –172
dBc/Hz @ Fourier frequency greater than 10 kHz. Both the input and output are matched to 50 ohms to obtain
better than 25 dB return loss. All RF outputs are AC coupled and the grounds are DC isolated to reduce the
effect of ground loops.
