LM2506 Features and Operation (Continued)

Application Information

SYSTEM CONSIDERATIONS

When employing the MPL SER/DES chipset in place of a

parallel bus, a few system considerations must be taken into

account. VDDIO levels of the Host and SER must be com-

patible. VDDIO levels of the DES and the Display must be

compatible. The LM2506 only supports rising edge clocking,

both the Host and Display must be compatible with this.

MPL SWAP FEATURE

The LM2506 provides a swap function of MPL MD lines

depending upon the state of the M/S* pin. This facilitates a

straight through MPL interface design eliminating the needs

for via and crossovers as shown on Figure 14. The parallel

bus pins are also swapped to facilitate a flow though orien-

tation of parallel bus signals.
