(1) All typicals are given for: V_CC = +3.3V and T_A = +25°C.
(2) These parameters are ensured by design. The limits are based on statistical analysis of the device over PVT (process, voltage,
temperature) ranges.
(3) C_L includes probe and fixture capacitance.
(4) Generator waveform for all tests unless otherwise specified: f = 1 MHz, Z_O = 50Ω, t_r ≤ 1 ns, t_f ≤ 1 ns (10%-90%).
(5) t_SKD1, |t_PHLD − t_PLHD|, is the magnitude difference in differential propagation delay time between the positive going edge and the negative
going edge of the same channel.
(6) t_SKD2 is the Differential Channel to Channel Skew of any event on the same device.
(7) t_SKD3, Differential Part to Part Skew, is defined as the difference between the minimum and maximum specified differential propagation
delays. This specification applies to devices at the same V_CC and within 5°C of each other within the operating temperature range.
(8) t_SKD4, part to part skew, is the differential channel to channel skew of any event between devices. This specification applies to devices
over recommended operating temperature and voltage ranges, and across process distribution. t_SKD4 is defined as |Max − Min|
differential propagation delay.
(9) f_MAX generator input conditions: t_r = t_f < 1 ns (0% to 100%), 50% duty cycle, 0V to 3V. Output criteria: duty cycle = 45%/55%, V_OD >
250mV, all channels switching.
