(1) Recommended input timing requirements are input specifications and not tested in production.
(2) T is the period of the PCLK.
(3) Typical values represent most likely parametric norms at 1.8 V or 3.3 V, TA = 25°C, and at Section 6.3 at the time of product characterization and are not verified.
(4) 0.45UI maximum when used with DS90UB934-Q1 deserializer. When used with DS90UB914A-Q1 deserializer, the maximum is 0.3UI.
(5) ƒPCLK denotes input PCLK frequency to the device.
(6) ƒOSC denotes input external oscillator frequency to the device (GPO3/CLKIN).
