3 / 12 page MC100ES6254/D TIMING SOLUTIONS 3 a. Absolute maximum continuous ratings are those maximum values beyond which damage to the device may occur. Exposure to these conditions or conditions beyond those indicated may adversely affect device reliability. Functional operation at absolute-maximum-rated conditions is not implied. Table 1. PIN CONFIGURATION Pin I/O Type Function CLK0, CLK0 Input LVPECL Differential reference clock signal input 0 CLK1, CLK1 Input LVPECL Differential reference clock signal input 1 OEA, OEB Input LVCMOS Output enable SEL0, SEL1 Input LVCMOS Clock switch select QA[0-2], QA[0-2] QB[0-2], QB[0-2] Output LVPECL Differential clock outputs (banks A and B) GND Supply GND Negative power supply VCC Supply VCC Positive power supply. All VCC pins must be connected to the positive power supply for correct DC and AC operation Table 2. FUNCTION TABLE Control Default 0 1 OEA 0 QA[0-2], Qx[0-2] are active. Deassertion of OE can be asynchronous to the reference clock without generation of output runt pulses QA[0-2] = L, QA[0-2] = H (outputs disabled). Assertion of OE can be asynchronous to the reference clock without generation of output runt pulses OEB 0 QA[0-2], Qx[0-2] are active. Deassertion of OE can be asynchronous to the reference clock without generation of output runt pulses QA[0-2] = L, QA[0-2] = H (outputs disabled). Assertion of OE can be asynchronous to the reference clock without generation of output runt pulses SEL0, SEL1 00 Refer to Table 3 Table 3.
