ADC-LD-BB/NOPB

ADC-LD-BB/NOPB EVALUATION MODULE.

The ADC-LD-BB/NOPB is an ADC low distortion Balun Board used to achieve single-ended-to-differential conversion. In case both I- and Q-inputs are simultaneously driven with a similar signal, an additional balun board of the same type may be desired. Incidentally, this board may also be used to do differential-to-single-ended conversion. This board may be used when observing the DCLK± or RCOut± signal on a single-ended scope when exploring the AutoSync feature on the GSPS ADC Reference Boards. The board uses the B0430J50100AHF from Anaren, which is designed for high-performance. Since the input impedance of the GSPS ADCs are 100R and the impedance of most signal generators are 50R, its 1:2 impedance ratio is very convenient. The 10pF capacitor at the input is recommended by Anaren for best performance. This balun is also a very good choice for driving the GSPS ADC sampling clock (CLK±).
