FMC Facility I2C Bus
11.1. FMC I2C EEPROM
A 2kbit I2C EEPROM (M24C02) is provided for FMC identification, as described in section 5.5 of
ANSI/VITA 57.1. It is at I2C address 0b1010000x and is connected to the FMC dedicated I2C pins at
J1-C30 (SCL) and J1-C31 (SDA). The pull-up resistors to 3V3_AUX are not populated (R148 and R149)
since the pull-ups should be provided on the carrier. The EEPROM is permanently enabled for writing.
The FMC identification EEPROM is programmed at the factory to enable automated identification,
verification, and configuration of Main Board parameters (typically VADJ voltage level). The contents of
the EEPROM are described in Appendix A.
Note:
The user must be cognizant that the FMC I2C EEPROM is always write-enabled. As it contains
critical information required for correct operation, one must never overwrite the factory settings.

ESD Protection
All MIPI SLVS differential signals as well as the GPIO and I2C ports are protected with Texas
Instruments TPD1E05U06DPYT unidirectional ESD protection devices located close to the MIPI
receptacles. They provide IEC 61000-4-2 level 4 protection and are very low capacitance (0.5pF typical)
designed for up to 6Gbps speed interfaces. Applied to 100-ohm differential lines, these devices introduce
less than 1dB insertion loss up to 2GHz (4Gbps).
