CLKN_DEL

CLKP_DEL

*) CLKN_POL/CLKP_POL controls have more better&easy clock margin adjustment.Use CLKN_POL/CLKP_POL at

first normally,especially for 27MHz/54MHz data output application.CLKN_DEL/CLKP_DEL are sometimes required

for 108MHz data output interface. CLKN_DEL/CLKP_DEL are not required for 27MHz/54MHz data output in most

cases.

CLKN_DEL

Control the clock delay of CLKNO pin.

0h/1h/3h/7h/Fh values are effective..The default value is “0”.

[REV_ID=0 TW2864]

1h:about 0.3ns more delay, 3h:about 0.6ns more delay,

7h:about 1.0ns more delay, Fh:about 1.3ns more delay

[REV_ID>=1 TW2864]

1h:about 2ns more delay, 3h:about 4ns more delay,

7h:about 6ns more delay, Fh:about 7ns more delay

CLKP_DEL

Control the clock delay of CLKPO pin.

0h/1h/3h/7h/Fh values are effective. The default value is “0”.

[REV_ID=0 TW2864]

1h:about 0.3ns more delay, 3h:about 0.6ns more delay,

7h:about 1.0ns more delay, Fh:about 1.3ns more delay

[REV_ID>=1 TW2864]

1h:about 2ns more delay, 3h:about 4ns more delay,

7h:about 6ns more delay, Fh:about 7ns more delay
