1.

Tristate is driven to logic high or logic low; there is no internal pull up or pull down resistor.

2.

LD is an open collector output requiring a 30k ohm pullup resistor to VDD. LD output is logic high under locked condition,

logic low for no input at fIN, and for “out-of-lock” condition LD transitions between logic low and logic high at the phase detector
