DLPS037F October 2014 – June 2021 DLPC900
The DLPC900 power delivery system provides two independent 1.8-V power sources. One of the 1.8-V power sources is used to supply 1.8-V power to the DLPC900 LVDS I/O and internal DRAM. Power for these functions must always be fed from a common source, which is recommended as a linear regulator. The second 1.8-V power source is used (along with appropriate filtering as discussed in the Section 10.1.2) to supply all of the DLPC900 internal PLLs (PLLD_VAD, PLLM1_VAD, and PLLM2_VAD). To keep this power as clean as possible, a dedicated linear regulator is highly recommended for the 1.8-V power to the PLLs.
