Note 4: 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, ΔVOD,
VTH and VTL which are differential voltages.
Note 5: When the device output is at TRI-STATE® the Deserializer will lose PLL lock. Resynchronization / Relock must occur before data transfer require t
Note 6: t
Note 7: UI – Unit Interval is equivalent to one serialized data bit width (1UI = 1 / 28*PCLK). The UI scales with PCLK frequency.
Note 8: t
Note 9: Supply noise testing was done with minimum capacitors on the PCB. A sinusoidal signal is AC coupled to the V
mVp-p measured at the device V
frequency on the Ser is less than 750 kHz. The Des on the other hand shows no error when the noise frequency is less than 400 kHz.
Note 10: Specification is guaranteed by characterization and is not tested in production.
Note 11: Specification is guaranteed by design and is not tested in production.
