Description
Clock Duty Cycle Stabilizer (DCS) Control Pin. CMOS compatible.
Do Not Connect. These pins should float.
CMOS-Compatible Output Logic Mode Control Pin.
Data Format Select Pin. CMOS control pin that determines the format of the output data.
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 1.7 V reference (3.4 V p-p analog
input range); connect to AVDD1 for external reference.
1.7 V Reference I/O. The function is dependent on the SENSE pin 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.
DCS = low (AGND) to enable DCS (recommended).
DCS = high (AVDD1) to disable DCS.
OUTPUT MODE = 0 for CMOS mode.
OUTPUT MODE = 1 (AVDD1) for LVDS outputs.
DFS = high (AVDD1) for twos complement.
DFS = low (ground) for offset binary format.
