ABSOLUTE MAXIMUM RATINGS
ELECTRICAL CHARACTERISTICS
(VCC = +3.0V to +3.6V, input data rate = 3.125Gbps, TA = 0°C to +85°C. Typical values are at VCC = +3.3V and TA = +25°C, unless
otherwise noted.)
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 in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
Supply Voltage, VCC..............................................-0.5V to +4.0V
Voltage at SDET .........................................-0.5V to (VCC + 0.5V)
Voltage at IN_±...........................................-0.5V to (VCC + 0.5V)
Current Out of OUT_±.......................................-25mA to +25mA
Continuous Power Dissipation (TA = +85°C)
44-Pin QFN-EP (derate 26.3mW/°C above +85°C)....2105mW
Operating Ambient Temperature Range ................0°C to +85°C
Storage Temperature Range .............................-55°C to +150°C
Lead Temperature (soldering, 10s) .................................+300°C
