Notes
1) Analog output voltage is factor adjustable up to 4 V
pp
at 10 MHz. See RF Output Level section on the next page
for more information.
2) Phase-offset control word is 12-bit wide.
3) Assuming a 50 MHz reference clock and a 300 MHz NCO frequency. Frequency control word is 28-bit wide.
4) On PCI boards, all 24 control bits are routed to on-board IDC header, and signals that are not used internally can
be utilized to control outside devices. Please contact SpinCore if you require more digital outputs; custom
designs with more output bits may be available.
5) This is the value seen without using termination. When the line is terminated with 50 Ω, the output voltage will be
lower.
6) This number can be larger on USB boards. Please contact SpinCore for custom design featuring a larger number
of instruction words.
7) Assuming a 50 MHz reference clock and a 75 MHz PulseBlaster timing core frequency.
8) The RF output can operate from direct current - DC (0 Hz) to 100 MHz. The analog output is DC coupled.
