I, 4-LEVEL,
LVCMOS
RATE control pin selects GEN 1,2 and GEN 3 operating modes.
Tie 1 kΩ to GND = GEN 1,2
FLOAT = AUTO Rate Select of Gen1/2 and Gen3 with de-emphasis
Tie 20 kΩ to GND = GEN 3 without de-emphasis
Tied 1 kΩ to VDD = RESERVED
Controls the internal Signal Detect Threshold.
See Table 5.

In 3.3-V mode, feed 3.3 V to VIN
In 2.5-V mode, leave floating
Power supply pins
2.5-V mode, connect to 2.5-V supply
3.3-V mode, connect 0.1-µF capacitor to each VDD pin (output of LDO)
Ground pad (DAP - die attach pad).

(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating
Conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) Absolute Maximum Numbers are specified for a junction temperature range of –40° C to 125° C. Models are validated to Maximum
Operating Voltages only.
(3) For soldering specifications: See application note SNOA549.
