8 CLOCK SIGNAL DISTRIBUTION AMPLIFIER, CSDA1 DESCRIPTION The CSDA1 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 CSDA1 contains a pulse distribution module with one input and five buffered outputs that can drive a 50ohm cable. The second module is a 5 MHz distribution amplifier with one input and five buffered outputs. The third module provides five isolated 10 MHz signals that are obtained by doubling the 5 MHz input signal. Each module contains an output level monitor LED located on the front panel. All the outputs power levels are monitored and compared to a preset threshold of +7dBm. If the signal level on any output drops below this threshold, the monitor LED for that module will turn off indicating a fault condition. The channeltochannel isolation in the RF distribution modules is typically 130 db and reverse isolation is typically 140 db. The phase noise of the modules is exceptionally low, typically Fourier frequency of 1 Hz and Fourier frequency greater than 10 khz. Both the input and outputs 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.

Upon failure of a selected input channel the amplifier switches over to the alternate RF input with a switching time less than 1 us. The selected RF input is buffered and distributed to ten unity gain outputs. The typical crosschannel isolation of the RF distribution is 140 db and reverse isolation is typically greater than 145 db.

32 LOW NOISE FREQUENCY REFERENCE, LNFR100E DESCRIPTION The LNFR100E is a high performance 10 MHz distributed frequency reference. It contains a 5 MHz SCcut ovenized oscillator, a low noise frequency doubler and a distribution amplifier module. The 10 MHz signal is distributed by the distribution amplifier to provide four 10 MHz outputs on the back panel. Typical cross channel isolation is 70 db and reverse isolation is typically greater than 75 db. The distribution module does not degrade the phase noise performance of the oscillator that is typically Fourier frequency of and Fourier frequency greater than 10 khz. The LNFR100E outputs are matched to 50 ohms to obtain better than 25 db return loss. The LNFR100E can be phase locked via an electrical tuning port or by providing an external 10 MHz reference.

34 LOW NOISE FREQUENCY REFERENCE, LNFR400 DESCRIPTION The LNFR400 is an ultralow noise frequency reference. The device can be used as a low noise source in phase noise measurement systems. Other applications include high stability frequency synthesizers, reference frequency generation and frequency synthesis chains for atomic standards. The LNFR 400 contains 5 MHz and 100 MHz ultralow noise ovenized oscillators. The outputs at 10 MHz, 20 MHz, 40 MHz and 80 MHz are obtained by multiplying the signal from the 5 MHz oscillator.
