DLPS031C December 2013 – August 2015 DLPC6401
PRODUCTION DATA.
Table 10 shows the recommended power delivery budget for DC offset and AC noise as observed at the corresponding DLPC6401 power pins.
ASIC POWER RAIL | USAGE | NOMINAL VOLTAGE | TOTAL SUPPLY MARGIN (1) |
---|---|---|---|
VDDC | ASIC core | 1.2 V | ±5% |
VDD12_PLLM/ VDD12_PLLD | Internal PLLs | 1.2 V | ±5% |
VDD_18_PLLM/ VDD18_PLLD | Internal PLLs | 1.8 V | ±5%(2) |
VDD_DMD | DMD LPDDR I/O | 1.9 V | ±5% |
VDD33 | LVCMOS I/O | 3.3 V | ±5% |
VDD12_FPD | FPD-Link LVDS I/F | 1.2 V | ±5% |
VDD33_FPD | FPD-Link LVDS I/F | 3.3 V | ±5% |
TI strongly recommends that the VDD_18_PLLM and VDD_18_PLLD power feeding internal PLLs be derived from an isolated linear regulator to minimize the AC noise component. It is acceptable for VDD12_PLLM and VDD12_PLLD to be derived from the same regulator as the core VDD12, but they should be filtered.
