Detailed Description The MAX3890 EV kit simplifies evaluation of the MAX3890. The EV kit operates from a +3.3V single supply and includes all the external components necessary to interface with LVDS inputs and 3.3V positivereferenced emitter-coupled logic PECL outputs. The LVDS inputs PDI_+, PDI_-, PCLKI+, PCLKI-, RCLK+, RCLK- ** are internally terminated with differential input resistance and therefore do not require external termination. Ensure that LVDS devices driving these inputs are not redundantly terminated. The LVDS outputs PCLKO+, PCLKO- require a differential termination with a resistor between complementary outputs. Do not terminate these outputs to ground. Layout Considerations The PECL outputs have voltage attenuation and impedance matching networks on the EV board that allow terminations to ground for oscilloscope interfacing. All signal inputs and outputs use coupled transmission lines. All input signal lines are of equal length to minimize propagation-delay skew. Likewise, all output signal lines are of equal length. **Note PCLKO±, PCLKI±, RCLK±, and SCLK± are labeled as PCKO±, PCKI±, RCK±, and SCK± on PC board.
