Description
Clock Duty Cycle Stabilizer (DCS) Control Pin. CMOS compatible. DCS = low (AGND) to enable
DCS (recommended); DCS = high (AVDD1) to disable DCS.
Do Not Connect. These pins should float.
CMOS-Compatible Output Logic Mode Control Pin. OUTPUT MODE = 0 for CMOS mode;
OUTPUT MODE = 1 (AVDD1) for LVDS outputs.
Data Format Select Pin. CMOS control pin that determines the format of the output data. DFS =
high (AVDD1) for twos complement; DFS = low (ground) for offset binary format.
Set Pin for LVDS Output Current. Place 3.7 kΩ resistor terminated to DRGND.
3.3 V (±5%) Analog Supply.
Reference Mode Selection. Connect to AGND for internal 1.6 V reference (3.2 V p-p analog
input range); connect to AVDD1 for external reference.
1.6 V Reference I/O. Function dependent on SENSE and external programming resistors.
Decouple to ground with 0.1 μF and 10 μF capacitors.
Analog Ground. The exposed heat sink on the bottom of the package must be connected to
AGND.
Differential Reference Output. Decoupled to ground with 0.1 μF capacitor and to REFB (Pin 11)
with 0.1 μF and 10 μF capacitors.
Differential Reference Output. Decoupled to ground with a 0.1 μF capacitor and to REFT
(Pin 10) with 0.1 μF and 10 μF capacitors.
5.0 V Analog Supply (±5%).
