(1) The Electrical Characteristics tables list verified specifications under the listed Recommended Operating Conditions except as otherwise modified or specified by the Electrical Characteristics Conditions and/or Notes. Typical specifications are estimations only and are not verified.
(2) Current into device pins is defined as positive. Current out of a device pin is defined as negative. Voltages are referenced to ground except VOD and ΔVOD which are differential voltages.
(3) Typical values represent most likely parametric norms at 1.8 V or 3.3 V, TA = 25°C, and at the Recommended Operation Conditions at the time of product characterization and are not verified.
(4) Specification is verified by design.
(5) Recommended Input Timing Requirements are input specifications and not tested in production.
(6) T is the period of the PCLK.
(7) FPD-Link device was designed primarily for point-to-point operation and a small number of attached slave devices. As such the Minimum IOL pullup current is targeted to lower value than the minimum IOL in the I2C specification.
(8) ƒPCLK denotes input PCLK frequency to the device.
(9) ƒOSC denotes input external oscillator frequency to the device (GPO3/CLKIN).
(10) The back channel frequency (MHz) listed is the frequency of the internal clock used to generate the encoded back channel data stream. The data rate (Mbps) of the encoded back channel stream is the back channel frequency divided by 2.
