5.3. POR of MGMT PHY (BCM54616S)
The detailed power-on reset (POR) flow is as follows:
1. 3.3V up and Ref clock up
2. 3.3V enable MPS1484 to generate 2.5V
3. All powers are stable, POWR607 inform CPLD
4. CPLD receive the signal, CPLD assert Reset_N high
5.4. I2C
The CPU board has three I2C channels for our application. The Channel 1 used for Power
Supply, Clock GEN, DC/DC, thermal sensor, CPLD2 and Fan CPLD. The channel 2 used for Power
Supply, CPLD 1,3, USB HUB, DC/DC, Multiplexer, Retimer, port 49~56 QSFP28 and port 57~58 SFP+.
The channel 2 used for port 1~48 SFP28.
