DS90UH947-Q1: Valid DOUT available after INITA?

Part Number: DS90UH947-Q1

Hi Team,

quick question and sanity check: To use a FPD3 SER (947, 949) and a DES (948) successfully we must make sure that the link is established and all parts are started following the correct procedure. To my understanding this means (simplified):

  1. Start SER
    1. VDDx power-up sequence
    2. pull PDB high
    3. INIT A
    4. valid OLDI CLK input
    5. INIT B
    6. achieve valid DOUT
  2. Start DES
    1. valid DIN from SER
    2. VDDx power-up sequence
    3. pull PDB high
    4. achieve LOCK status

DES must not start before SER has achieved valid DOUT. SER will achieve valid DOUT only after completing INIT B (1.e) as described above, never after only INIT A (1.c, 1.d).

Is this correct? Thanks, best regards,

 Johannes.
