Evaluation Board Kit Contents
The evaluation board is typically shipped with a parallel port cable that is used to interconnect the board
to a PC LPT port, enabling the board to be programmed. The kit may also include one or more BALUN
boards. Each BALUN board is configured to accept a differential signal input and provide a single-ended
signal output. This enables the differential clock outputs of the LMK040xx to be connected to test
equipment or to drive single-ended circuits. The user should be aware that there is some attenuation of
the clock signal when using these boards.
NOTE: If the board contains an ADT2-1T BALUN, DC bias on the input signals is blocked at the
output. If the board contains an ADTL2-18, DC bias on the input will be passed to the output. This
may be unacceptable for some types of test equipment.
Appendix F contains typical frequency response data for the BALUN boards.
