VDDA
Power
Power supply for PLL core.
Tri-level input to select High BW, Bypass or Low BW Mode. Has an internal 120kΩ
pull-up resistor. See PLL Operating Mode table for details.
^HIBW_BYPM_LOBW#

Latched In
Input
3
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 120kΩ pull-up resistor.

GND
GND
Ground pin.
Power supply for differential input clock (receiver). This V should be treated as an
analog power rail and filtered appropriately. Nominally 3.3V.

HCSL true input.
HCSL complementary input.
8
Data pin of SMBUS circuitry.
9
Input
Clock pin of SMBUS circuitry.
10
Complementary half of differential feedback output. This pin should NOT be connected
to anything outside the chip. It exists to provide delay path matching to get 0
propagation delay.
FBOUT_NC#
Output
11
True half of differential feedback output. This pin should NOT be connected to anything
outside the chip. It exists to provide delay path matching to get 0 propagation delay.
