Other Parts Discussed in Thread: TPS53622
Hi,
As I mentioned in my last queries.
We are using TPS53659 and TPS53622 multiphase regulators in our design to power on the Intel Xeon Processor D-1746TER (Idaville).
I have a few doubts, please help me out.
1) As Intel need a default core supply voltage before it asserts any SVID command that is VBOOT voltage (it is usually 1.2V or 1V). Now please tell me what is the default VBOOT of both the regulators?
2) If the default VBOOT voltage is different from the desired Vboot of the processor then will we have to program the voltage regulator before enabling it (AVR_ON)?
3) We have connect the SVID interface of VR with SVID lanes of processor and PMBus interface of VR with PMBus over the processor itself. Do we need to add one Header (connector) for PMBus to connect the Digital Fusion Power Module?
4) If this Fusion Power Module is required to connected, in this case do we need to keep the VR's output in disabled mode (AVR_EN) low?
5) We are using both the channels (A & B). we want to enable/disable both the channel individually on different timing. How BEN_VCCIO can be used as BVR_EN?
Thank You
