Description

3

OutV /

SCLK

Output Voltage Amplitude and Serial Interface Clock.

Tie this pin high for normal differential DCLK and data

amplitude. Ground this pin for a reduced differential

output amplitude and reduced power consumption. See

Section 1.1.6. When the extended control mode is

enabled, this pin functions as the SCLK input which

clocks in the serial data. See Section 1.3

4

OutEdge /

DDR /

SDATA

DCLK Edge Select, Double Data Rate Enable and

Serial Data Input. This input sets the output edge of

DCLK+ at which the output data transitions. (See

Section 1.1.5.2). When this pin is floating or connected

to 1/2 the supply voltage, DDR clocking is enabled.

When the extended control mode is enabled, this pin

functions as the (SDATA) input. See Section 1.2 for

details on the extended control mode.

15

DCLK_RST

DCLK Reset. A positive pulse on this pin is used to

reset and synchronize the DCLK outputs of multiple

converters. See Section 1.5 for detailed description.

26

PD

Power Down Pin. A logic high on the PD pin puts the

device into the Power Down Mode.

30

CAL

Calibration Cycle Initiate. A minimum 80 input clock

cycles logic low followed by a minimum of 80 input

clock cycles high on this pin initiates the self calibration

sequence. See Section 2.4.2.

14

FSR/ECE

Full Scale Range Select and Extended Control Enable.

In non-extended control mode, a logic low on this pin

sets the full-scale differential input range to 650 mV

P-P.

A logic high on this pin sets the full-scale differential

input range to 870 mV

P-P. See Section 1.1.4. To enable

the extended control mode, whereby the serial interface

and control registers are employed, allow this pin to

float or connect it to a voltage equal to V

A/2. See

Section 1.2 for information on the extended control

mode.

127

CalDly /

SCS

Calibration Delay and Serial Interface Chip Select. With

a logic high or low on pin 14, this pin functions as

Calibration Delay and sets the number of input clock

cycles after power up before calibration begins (See

Section 1.1.1). With pin 14 floating, this pin acts as the

enable pin for the serial interface input and the CalDly

value becomes "0" (short delay with no provision for a

long power-up calibration delay).
