Table 4–40 shows the high-speed I/O timing specifications for HC210W

F484 WireBond devices.

PLL multiplication factor

tRISE

Low-to-high transmission time.

tFALL

High-to-low transmission time.

Timing unit interval (TUI)

The timing budget allowed for skew, propagation delays, and data

sampling window. (TUI = 1/(Receiver Input Clock Frequency ×

Multiplication Factor) = tC/w).

fHSDR

Maximum/minimum LVDS data transfer rate (fHSDR = 1/TUI), non-DPA.

fHSDRDPA

Maximum/minimum LVDS data transfer rate (fHSDRDPA = 1/TUI), DPA.

Channel-to-channel skew (TCCS)

The timing difference between the fastest and slowest output edges,

including tCO variation and clock skew. The clock is included in the

TCCS measurement.

Sampling window (SW)

The period of time during which the data must be valid in order to

capture it correctly. The setup and hold times determine the ideal strobe

position within the sampling window.

Input jitter (peak-to-peak)

Peak-to-peak input jitter on highspeed PLLs.

Output jitter (peak-to-peak)

Peak-to-peak output jitter on highspeed PLLs.

tDUTY

Duty cycle on highspeed transmitter output clock.

tLOCK

Lock time for highspeed transmitter and receiver PLLs.
