With respect to the C6457 LJCB termination:
SPRAAV7B: DSPs Hardware Design Guide, Figure 3 indicates that "any unused LJCB inputs should be connected to produce a valid logic level. The recommended connections are shown in Figure 3. The 1-kΩ resistor is to reduce power." The connection is shown to 1.1v.
The TMS320C6457 Data Manual (SPRS582B) shows in Table 6-4 hat the LJCB I/O buffer is connected to the Supply Core Voltage. We are using 1.2V for the core.
My question is; Should we connect to 1.1V or 1.2 V for “terminating” the unused LJCB?
Thank you, Bryan Busacco
