TIMING CHARACTERISTICS
Detailed timing diagrams for the TL3M device are illustrated in Figures
intervals tabulated below the diagrams. All output times are measured with a maximum 25 pF load capaci-
tance. Timing parameters are measured at voltage levels of (V
output signals.
Note 1: 22.35 ns (DS3) or 29.10 ns (E3).
TCLKn clock period
TCLKn duty cycle, t
TPOSn/TNEGn setup time before TCLKn
TPOSn/TNEGn hold time after TCLKn
RnNRC clock period
RnNRC duty cycle, t
RnNRD output delay after RnNRC

Shown for control bit INVCI (bit 5 in XC1H) equal to 0; data is clocked in on the falling edge
when INVCI equals 1. RnNRD is always clocked out on the rising edges of RnNRC. The delay
between the input clock TCLKn and output clock RnNRC is not specified.
