Description
0x0A4 [2:0] OUT5 ramp current
Ramp current for the delay function. The combination of the number of capacitors and the ramp
current sets the delay full scale.
2 1 0 Current (µA)
0 0 0 200 (default)
0 0 1 400
0 1 0 600
0 1 1 800
1 0 0 1000
1 0 1 1200
1 1 0 1400
1 1 1 1600
0x0A5 [5:0] OUT5 delay fraction
Selects the fraction of the full-scale delay desired (6-bit binary).
A setting of 000000b gives zero delay.
Only delay values up to 47 decimals (101111b; 0x2F) are supported (default = 0x00).
0x0A6 0
OUT6 delay bypass Bypasses or uses the delay function.
0: uses delay function.
1: bypasses delay function (default).
0x0A7 [5:3] OUT6 ramp capacitors Selects the number of ramp capacitors used by the delay function. The combination of the
number of capacitors and the ramp current sets the delay full scale.
5 4 3 Number of Capacitors
0 0 0 4 (default)

0x0A8 [5:0] OUT6 delay fraction
Selects the fraction of the full-scale delay desired (6-bit binary).
A setting of 000000b gives zero delay.
Only delay values up to 47 decimals (101111b; 0x2F) are supported (default = 0x00).
0x0A9 0
OUT7 delay bypass Bypasses or uses the delay function.
0: uses delay function.
1: bypasses delay function (default).
