Notes:
35. Since this timing parameter is greater than the minimum time period of REFCLK it sets an upper limit to the frequency in which REFCLKx can be used to clock
the receive data out of the output register. For predictable timing, users can use this parameter only if REFCLK period is greater than sum of t
and set-up
time of the upstream device. When this condition is not true, RXCLKC± or RXCLKA± (a buffered or delayed version of REFCLK when RXCKSELx = LOW)
could be used to clock the receive data out of the device.
36. This parameter is 649 ps for CYW15G0201DXB.
37. While sending continuous K28.5s, outputs loaded to a balanced 100
load, measured at the cross point of the differential outputs over the operating range.
38. 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.
39. Total jitter is calculated at an assumed BER of 1E
12. Hence: Total Jitter (t
)
=
(t
* 14) + t
.
40. 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.
41. Receiver UI (Unit Interval) is calculated as 1/(f
REF
*20) (when RXRATE
=
HIGH) or 1/(f
REF
* 10) (when RXRATE
=
LOW) if no data is being received, or 1/(f
REF
* 20)
(when RXRATE
=
HIGH) or 1/(f
REF
* 10) (when RXRATE
=
LOW) of the remote transmitter if data is being received. In an operating link this is equivalent to t
B.
