Part Number: AM263P4-Q1
Other Parts Discussed in Thread: AM263P4, SN74LV1T34
Tool/software:
On the AM263P4 part, (full part number AM263P4ACOKFZCZRQ1) , pin R6 is VDDA18V_LDO, which is an LDO output providing 1.8 volts to be connected to the VDDA18 pins and, through a ferrite bead, the VDDA18_OSC_PLL pin on the part. How much current can the VDDA18V LDO provide?
I noticed in the Design guidelines, Figure 3.2 - Excerpt from AM263X control card schematics- Oscillator Clock Sources ... , it shows this LDO voltage powering a SN74LV1T34 buffer. The buffer is receiving a 25MHz clock signal from a 3.3V oscillator and stepping it down to 1.8V for the AM263P4 part. I was wondering if the LDO voltage could power an oscillator ( as opposed to just a buffer) which would require 100 milli amps or so. Note the buffer only requires 10 micro amps, which is considerably less than 100 milli amps.
