DESCRIPTION
3.3-V analog power supply. Needs close decoupling capacitor.
Analog 3.3-V supply ground
Active-low. A back-end error sequence is generated by applying logic
LOW to this terminal. This pin is connected to an external power
stage. If no external power stage is used, connect this pin directly to
DVDD.

TYPE: A = analog; D = 3.3-V digital; P = power/ground/decoupling; I = input; O = output
All pullups are 20-µA
weak
pullups and all pulldowns are 20-µA
weak
pulldowns. The pullups and pulldowns are included to assure
proper input logic levels if the terminals are left unconnected (pullups
→
logic 1 input; pulldowns
→
logic 0 input). Devices that drive
inputs with pullups must be able to sink 50
µA
while maintaining a logic-0 drive level. Devices that drive inputs with pulldowns must be
able to source 50
µA
while maintaining a logic-1 drive level.
