TYPE(1)

DESCRIPTION

NAME(2) (3)

NO.

^PWRGD/PWRDN#

Power Good/Power Down Active Low. Multifunctional input pin. Internal pullup resistor.

On the first low-to-high transition, functions as Power Good pin which starts up the device

On the subsequent low/high transitions, functions as Power Down Active Low pin which

controls the device to enter or exit power-down mode.

Low = power-down mode

High = normal operation mode

vSBI_EN

SBI Enable. Internal pulldown resistor. Do not change the state of this pin after power-up.

Low at power-up = SBI interface disabled. Pin 16, 18, 25 and 34 function as OE pins.

High at power-up = SBI interface enabled. Pin 16, 18, 25 and 34 function as SBI interface

pins. SMBus and other OE pins remain functional.

^vSADR1_tri

SMBus Address 3-level input pin. Internal pullup and pulldown resistors.

^vSADR0_tri

SMBus Address 3-level input pin. Internal pullup and pulldown resistors.

vZOUT_SEL

LP-HCSL differential clock output impedance select. Internal pulldown resistor.

Low = 85Ω.

High = 100Ω.

LOS#

Loss of Input Clock Signal Active Low/No Connect. Open drain. Requires external pullup

resistor.

Low = Invalid input clock.

High = Valid input clock.

SMB_DATA

I/O

SMBus Data. Requires external pullup resistor. No connect if unused.

SMB_CLK

SMBus Clock. Requires external pullup resistor. No connect if unused.

(1)

I = Input, O = Output, I/O = Input or Output, G = Ground, P = Power, NC = No Connect

(2)

Pins with a "^" prefix have an internal pullup resistor. Pins with a "v" prefix have an internal pulldown resistor. Pins with a "^v" have an

internal pullup resistor and an internal pulldown resistor so that mid level is selected when the pin is left floating. Pins with "^/v" have an

internal pullup or pulldown based on selected function.

(3)

The "#" symbol indicates active low.
