NAME
CLKTYP
OVDD
FUNCTION
Clock Type Definition Input. Connect CLKTYP to GND to define the single-ended clock input. Connect
CLKTYP to OVDD or VDD to define the differential clock input.
Output Driver Power Input. Connect OVDD to a 1.7V to VDD power supply. Bypass OVDD to GND with a
parallel capacitor combination of ≥2.2µF and 0.1µF.
DOR
Data Out-of-Range Indicator. The DOR digital output indicates when the analog input voltage is out of
range. When DOR is high, the analog input is beyond its full-scale range. When DOR is low, the analog
input is within its full-scale range.

No Connect. Leave N.C. unconnected.
DAV
Data Valid Output. The DAV is a single-ended version of the input clock that is compensated to correct
for any input clock duty-cycle variations. DAV is typically used to latch the MAX1211 output data into an
external back-end digital circuit.
PD
REFOUT
REFIN
G/T
EP
Power-Down Input. Force PD high for power-down mode. Force PD low for normal operation.
Internal Reference Voltage Output. For internal reference operation, connect REFOUT directly to REFIN
or use a resistive divider from REFOUT to set the voltage at REFIN. Bypass REFOUT to GND with a
≥0.1µF capacitor.
Reference Input. VREFIN = 2 x (VREFP - VREFN). Bypass REFIN to GND with a ≥0.1µF capacitor.
Output Format Select Input. Connect G/T to GND for the two’s complement digital output format. Connect
G/T to OVDD or VDD for the Gray code digital output format.
Exposed Paddle. EP is internally connected to GND. Externally connect EP to GND to achieve specified
performance.
