MAX9257A/MAX9258A
Fully Programmable Serializer/Deserializer
with UART/I2C Control Channel
MAX9258A AC ELECTRICAL CHARACTERISTICS (continued)
(VCC_ = +3.0V to +3.6V, VCCIO = +1.71V to +3.6V, RL = 50I Q1%, CL = 8pF, differential input voltage |VID| = 0.1V to 1.2V, input
common-mode voltage VCM = |VID/2| to VCC - |VID/2|, TA = -40NC to +105NC, unless otherwise noted. Typical values are at VCC_ =
+3.3V, |VID| = 0.2V, VCM = 1.2V, TA = +25NC) (Notes 5, 6 and 7)
Note 2: Current into a pin is defined as positive. Current out of a pin is defined as negative. All voltages are referenced to ground
except VTH and VTL.
Note 3: Maximum and minimum limits over temperature are guaranteed by design and characterization. Devices are production
tested at TA = +105NC.
Note 4: One output at a time.
Note 5: AC parameters are guaranteed by design and characterization, and are not production tested.
Note 6: CL includes probe and test jig capacitance.
Note 7: tT is the period of the PCLK_OUT.
Note 8: For high-speed mode timing, see the Detailed Description section.
Note 9: I2C timing parameters are specified for fast-mode I2C. Max data rate = 400kbps.
Typical Operating Characteristics
(VCC_ = +3.3V, RL = 50O, CL = 8pF, TA = +25NC, unless otherwise noted.)
