(1) Typical Values are given for VCC = 3.3 V and TA = 25ºC
(2) Receiver Skew Margin is defined as the valid data sampling region at the receiver inputs. This margin takes into account the transmitter pulse positions (min and max) and the receiver input setup and hold time (internal data sampling window - RSPos). This margin allows for LVDS interconnect skew, inter-symbol interference (both dependent on type/length of cable), and clock jitter (less than 250 ps).
(3) Total latency for the channel link chipset is a function of clock period and gate delays through the transmitter (TCCD) and receiver (RCCD). The total latency for the DS90CR215/DS90CR285 transmitter and DS90CR216A/DS90CR286A receiver is: (T + TCCD) + (2*T + RCCD), where T = Clock period.

C—Setup and Hold Time (Internal data sampling window) defined by Rspos (receiver input strobe position) min and max

Tppos—Transmitter output pulse position (min and max)

Cable Skew—typically 10 ps–40 ps per foot, media dependent

RSKM = Cable Skew (type, length) + Source Clock Jitter (cycle to cycle)(1) + ISI (Inter-symbol interference)(2)
1. Cycle-to-cycle jitter depends on the Tx source. if a Channel Link I Source Transmitter is used, clock jitter is maintained to less than 250 ps at 66 MHz.
2. ISI is dependent on interconnect length; may be zero.
