Characteristic Description
Auxiliary Output pulse width, typical Pulse width varies, 1 s minimum
External reference Run SPC whenever the ext ernal ref erence is more than 2000 ppm different
than the internal reference or the reference at which SPC was last run.

Serial data output baud rate range (CSA7000B Series
only)
Fbaud <1250 MBd. Output swing of 1010 repeating pattern at this baud will
be at least 200 mV into 50 Ω.
Serial clock output frequency range (CSA7000B Series
only)
Peak-to-peak output swing at 625 M H z is at least 200 mV p-p into 50 Ω.
Higher frequencies are further attenuated by approximately 6 dB per octave
above 625 MHz.
Use AC or DC coupled 50 Ω termination; AC coupling the clock provides
about 10% more amplitude.
Serial data and clock output voltages, typical
(CSA7000B Series onl y)
Voh=--1.0V
Vol = --1.7 V
Assumes a load impedance greater than 1 kΩ.(50Ω source terminati on.)
If a 50 Ω or 75 Ω load is used, either use a DC blocking capacitor in series
with the signal or reference the termination to about --1.3 V. The signal
amplitude will be correspondingly reduced.
Serial data output latency, typical (CSA7000B Series
only)
11 ns ±4 ns plus 35.5 clock cycles
