*LTC1403 timing from board with 10MHz crystal.
*
*10MHz, divided from 40MHz, forced to CLKIN by 1403 board.
*
*Horizontal scale is 25ns/chr or 100ns period at BCLKR
*
*Timing measured at DSP pins. Jxx pin labels for jumper cable.

* negative edge BCLKR
* negative BFSR pulse
* no data shifted
* 1’ cable from counter to CONV at DUT
* 2’ cable from counter to CLK at DUT
*No right shift is needed to right justify the input data in the main program
*
*the two msbs should also be masked
