Note that with this termination, the DAC side of the transformer is not 50- Ω terminated and therefore may result in reflections when used with a cable output. Figure 63 shows a schematic of the equivalent CMOS digital inputs of the DAC5687. DA[15:0], DB[15:0], SLEEP, PHSTR, TXENABLE, QFLAG, SDIO, SCLK, and SDENB have pulldown resistors and RESETB has a pullup resistor internal to the DAC5687. See the specification table for logic thresholds. The pullup and pulldown circuitry is approximately equivalent to 100 k Ω. Figure 63. CMOS/TTL Digital Equivalent Input Figure 64 shows an equivalent circuit for the clock input. Figure 64. Clock Input Equivalent Circuit Figure 65, Figure 66, and Figure 67 show various input configurations for driving the differential clock input (CLK/CLKC).
