(1) The Electrical Characteristics tables list ensured 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 ensured.
(2) Typical values represent most likely parametric norms at VDD = 3.3 V, Ta = +25ºC, and at the Recommended Operation Conditions at the time of product characterization and are not ensured.
(3) 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.
(4) tPLD is the time required by the device to obtain lock when exiting power-down state with an active PCLK.
(5) UI – Unit Interval is equivalent to one serialized data bit width (1UI = 1/35*PCLK). The UI scales with PCLK frequency.
(6) Supply noise testing was done with minimum capacitors on the PCB. A sinusoidal signal is AC coupled to the VDD33 and VDDIOsupplies with amplitude = 100 mVp-p measured at the device VDD33 and VDDIO pins. Bit error rate testing of input to the Ser and output of the Des with 10 meter cable shows no error when the noise frequency on the Ser is less than 50 MHz. The Des on the other hand shows no error when the noise frequency is less than 50 MHz.
(7) Specification is ensured by characterization and is not tested in production.
(8) Specification is ensured by design and is not tested in production.
(9) Jitter Frequency is specified in conjunction with DS90UH926 PLL bandwidth.
