Browse Our Clocks & Oscillators. At Bliley, we've been making industry-leading frequency control devices for almost 100 years.Hi, We currently have a board with a Spartan3A-1400 interfacing with an ADC that generates LVDS data at 250MHz. An alternate analog front-end is being designed and the analog chip designers have asked if they could use a 3.3V CMOS interface running at the same speed of 250MHz. Initially, we chose an LVDS interface as it seemed the right thing to do for "high .(b). Noninverted Output. Figure 1. Typical CMOS digital output driver. Since the input impedance is high and the output impedance is relatively low, an advantage that CMOS has is that one output can typically drive multiple CMOS inputs. Engineers and system designers now have three options to consider when designing in their FPGA-to-converter links – low-voltage differential signaling (LVDS), CMOS and JESD204B. Since converter resolution and speed have increased, there is a growin.
