Note 1: All voltages are referenced to ground. Current into the IC is positive, and current out of the IC is negative.
Note 2: Secondary power supply is used to support optional variable power-supply feature of the XFP module. If V
Note 3: Input signals (i.e., TX-D, MOD-DESEL, and P-DOWN/RST) have internal pullup resistors.
Note 4: Guaranteed by design. Simulated over process and 50μA < I
Note 5: C
Note 6: EEPROM write begins after a STOP condition occurs.
Note 7: This is the maximum and minimum voltage on the MODSET and BIASSET pins required to meet accuracy and drift specifi-
Note 8: For V
Note 9: This is the uncalibrated offset provided by the factory; offset adjustment is available on this channel.
Note 10: %FS refers to calibrated FS in case of internal calibration, and uncalibrated FS in the case of external calibration.
