Power Connection
The CLC001 evaluation board is powered by externally supplying 3.3V ±10% (4V
Max) to VDD with respect to GND.
Input Interfacing
The CLC001 evaluation board schematic is shown above in Figure 1. The board is
initially set up for 75 , AC-coupled, single-ended input. It may be configured for
DC-coupled LVDS or twisted pair cable by removing R1 and R2, shorting across C9
and C10, and inserting the correct termination resistor for R11 (typically between
100 and 120 ). No jumper should be used on P1 for DC-coupled applications. A
center tap capacitance termination may be implemented by removing the short on
C8 and inserting a 0.1uF capacitor.
DC Bias is applied to the inputs with the proper placement of jumpers on P1. With
no jumpers installed, no bias voltage is supplied and the part must be DC-coupled.
The CLC001 Evaluation Board allows for two methods of applying DC bias to the
input:
