Note 1:
DS3 mode.
Note 2:
E3 mode.
Note 3:
STS-1 mode.
Note 4:
Outputs loaded with 25pF, measured at 50% threshold.
Note 5:
Not tested during production test.
Note 6:
When TCINV = 0, TPOS/TDAT and TNEG are sampled on the rising edge of TCLK. When TCINV = 1, TPOS/TDAT and TNEG
are sampled on the falling edge of TCLK.
Note 7:
When RCINV = 0, RPOS/RDAT and RNEG/RLCV are updated on the falling edge of RCLK. When RCINV = 1, RPOS/RDAT and
RNEG/RLCV are updated on the rising edge of RCLK.
Note 8:
Outputs loaded with 25pF, measured between VOL (max) and VOH (min).
Note 9:
Measured between VIL (max) and VIH (min).
