Welcome to the MSEE Thesis Board DAC Delay web page. This page
contains information on the approximate IODELAY taps required on the
DAC Read and Write signals. The Perl code for used to implement
the table below is provided in a gzip'd tar-ball: dac_iodelay.tgz.
DAC Signal IODELAY Taps:
- Matched Length Group #1: SIG_DML1_CON, Reference Signal: FPGA_DAC_CLK_P
| Signal Name | Length (Mils) | ML Group | Is Reference | Average Length (Mils) | Length (ps) | Added Delay (ps) | Number of Taps Needed | Number of Taps Needed (Normalized) |
