NOTE:
AC COUPLING CAPACITORS SHOULD BE USED TO CONNECT DATA OUTPUTS
TO DATA INPUTS BETWEEN THE AFBR-732BWZ, AFBR-742BZ, AND HOST BOARD
ICs (e.g., ASIC) WITH EITHER 50 W SINGLE-ENDED OR 100
DIFFERENTIAL
TERMINATIONS AS SHOWN. THE CAPACITORS' VALUES CAN BE REDUCED FROM
100 nF (0603 SIZE) IF THE DATA RATE AND RUN LENGTH ARE LIMITED.
