^CKPWRGD_PD#

Input

Input notifies device to sample latched inputs and start up on first high

assertion. Low enters Power Down Mode, subsequent high assertions

exit Power Down Mode. This pin has internal pull-up resistor.

^vSS_EN_tri

Latched In

Latched select input to select spread spectrum amount at initial power

up. See Spread Selection table.

BCLK0#

Output

Complement output of differential BCLK.

BCLK1

Output

True output of differential BCLK.

BCLK1#

Output

Complement output of differential BCLK.
