DEMO MANUAL DC2183A
Encode Termination
– Enables or disables LVDS internal
termination:
•
Disabled (Default) – Disables internal termination
•
Enabled – Enables internal termination
LVDS Current
– Selects the LVDS output drive current:
•
1.75mA - LVDS output driver current
•
2.1mA - LVDS output driver current
•
2.5mA - LVDS output driver current
•
3.0mA - LVDS output driver current
•
3.5mA (Default) - LVDS output driver current
•
4.0mA - LVDS output driver current
•
4.5mA - LVDS output driver current
Two’s Complement
– Enables two’s complement mode:
•
Enabled (Default) – Selects two’s complement mode
•
Disabled – Selects offset binary mode
Randomizer
– Enables data output randomizer:
•
Disabled (Default) – Disables data output randomizer
•
Enabled – Enables data output randomizer
ABP
– Alternate Bit Polarity (ABP) mode:
•
Disabled (Default) – Disables alternate bit polarity
•
Enabled – Enables alternate bit polarity (Before enabling
ABP, be sure the part is in offset binary mode)
Output Test
– Selects digital output test patterns:
•
None (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 D15-D0 alternate between 1
0101 0101 1010 0101 and 0 1010 1010 0101 1010
on alternating samples
•
Alternating – Digital outputs alternate between all 1s
and all 0s on alternating samples
Once the desired settings are selected hit OK and PScope
will automatically update the register of the device on the
DC2183 demo board.
