DEMO MANUAL DC1620A
• Double LVDS (Default) – double data rate LVDS output
mode
• Double CMOS – double data rate CMOS output mode
(This mode is not supported by the DC1620A)
Test Pattern:
Selects Digital output test patterns.
• Off (Default) – ADC data presented at output
• All out =1 – All digital outputs are 1
• All out = 0 – All digital outputs are 0
• Checkerboard - OF, and D13-D0 Alternate between 101
0101 1010 0101 and 010 1010 0101 1010 on alternat-
ing samples
• Alternating – Digital outputs alternate between all 1’s
and all 0’s on alternating samples
QUICK START PROCEDURE
Alternate Bit:
Alternate bit polarity (ABP) Mode.
• Off (Default) – Disables alternate bit polarity
• On – Enables alternate bit polarity (before enabling ABP,
be sure the part is in offset binary mode)
Randomizer:
Enables data output randomizer.
• Off (Default) – Disables data output randomizer
• On – Enables data output randomizer
Two’s complement:
Enables two’s complement mode.
• Off (Default) – Selects offset binary mode
• On – Selects two’s complement mode
Once the desired settings are selected hit OK and PScope
will automatically update the register of the device on the
DC1620A demo board.
