Table 55. Fine Delay Adjust—OUT6 to OUT9

Reg.

Addr.

(Hex) Bits Name Description

0x0A0 0 OUT6 delay bypass Bypasses or uses the delay function.

0: uses delay function.

1: bypasses delay function (default).

0x0A1 [5:3] OUT6 ramp capacitors Selects the number of ramp capacitors used by the delay function. The combination of the

number of the capacitors and the ramp current sets the delay full scale.

Number of Capacitors

0 0 0 4 (default)

0 0 1 3

0 1 0 3

0 1 1 2

1 0 0 3

1 0 1 2

1 1 0 2

[2:0] OUT6 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)

400

600

0 1 1 800

1 0 0 1000

1 1 1 1600

0x0A2 [5:0] OUT6 delay fraction Selects the fraction of the full-scale delay desired (6-bit binary).

A setting of 000000 gives zero delay.

Only delay values up to 47 decimals (101111b; 0x2F) are supported (default = 0x00).

0x0A3 0 OUT7 delay bypass Bypasses or uses the delay function.

0: use delay function.

1: bypass delay function (default).

0x0A4 [5:3] OUT7 ramp capacitors Selects the number of ramp capacitors used by the delay function. The combination of the
