Note:
1. The symbols used for timing specifications herein follow the pattern of t(First two letters of functional block)(signal)(state) (reference)(state)
for inputs and t(First two letters of functional block)(reference)(state)(signal)(state) for outputs. For example, tLBIXKH1 symbolizes local bus
timing (LB) for the input (I) to go invalid (X) with respect to the time the tLBK clock reference (K) goes high (H), in this case for
clock one(1). Also, tLBKHOX symbolizes local bus timing (LB) for the tLBK clock reference (K) to go high (H), with respect to the
output (O) going invalid (X) or output hold time.
2. All timings are in reference to LSYNC_IN for PLL enabled and internal local bus clock for PLL bypass mode.
3. All signals are measured from BVDD/2 of the rising edge of LSYNC_IN for PLL enabled or internal local bus clock for PLL
bypass mode to 0.4
× BVDD of the signal in question for 2.5-V signaling levels.
4. Input timings are measured at the pin.
5. For purposes of active/float timing measurements, the Hi-Z or off state is defined to be when the total current delivered through
the component pin is less than or equal to the leakage current specification.
6. tLBOTOT is a measurement of the minimum time between the negation of LALE and any change in LAD. tLBOTOT is
programmed with the LBCR[AHD] parameter.
7. Maximum possible clock skew between a clock LCLK[m] and a relative clock LCLK[n]. Skew measured between
complementary signals at BVDD/2.
8. Guaranteed by design.
