Notes:
38. This parameter is 649 ps for CYW15G0401DXB
39. While sending continuous K28.5s, outputs loaded to a balanced 100Ω load, measured at the cross point of differential outputs, over the operating range.
40. While sending continuous K28.7s, after 100,000 samples measured at the cross point of differential outputs, time referenced to REFCLK input, over the
operating range.
41. Total jitter is calculated at an assumed BER of 1E –12. Hence: total jitter (tJ) = (tRJ * 14) + tDJ.
42. Also meets all Jitter Generation and Jitter Tolerance requirements as specified by SMPTE 259M, SMPTE 292M, OBSAI RP3, CPRI, ESCON, FICON, Fibre
Channel and DVB-ASI.
43. Receiver UI (Unit Interval) is calculated as 1/(fREF * 20) (when RXRATE = HIGH) or 1/(fREF * 10) (when RXRATE = LOW) if no data is being received, or
1/(fREF * 20) (when RXRATE = HIGH) or 1/(fREF * 10) (when RXRATE = LOW) of the remote transmitter if data is being received. In an operating link this is
equivalent to tB.
