Note:
1. The symbols used for timing specifications 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. Maximum possible clock skew between a clock LCLK[m] and a relative clock LCLK[n]. Skew measured between
complementary signals at BVDD/2. Skew number is valid only when LCLK[m] and LCLK[n] have the same load.
3. All signals are measured from BVDD/2 of the edge of local bus clock to 0.4 × BVDD of the signal in question for 3.3-V signaling
levels.
4. Input timings are measured at the pin.
5. The value of tLBOTOT is the measurement of the minimum time between the negation of LALE and any change in LAD.
6. 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.
7. Guaranteed by design.
