Pin and signal description
LA[00..33]_P,
LA[00..33]_N		 LA_XX - LPC, FPGA Bank A,
68 user-defined, single-ended signals or 34 user-defined, differential pairs (mandatory for LPC)


HA[00..23]_P,
HA[00..23]_N		 HA_XX - HPC, FPGA Bank A,
48 user-defined, single-ended signals or 24 user-defined, differential pairs


HB[00..21]_P,
HB[00..21]_N		 HB_XX - HPC, FPGA Bank B,
44 user-defined, single-ended signals or 22 user-defined, differential pairs


XX_P_CC,
XX_N_CC		 User-defined clock capable (CC) pins. These pins can be used for clock signals.


CLK[0..1]_M2C_P,
CLK[0..1]_M2C_N		 2 user clocks, differential pairs, driver is the mezzanine module


CLK[2..3]_BIDIR_P,
CLK[2..3]_BIDIR_N		 2 user clocks, differential pairs, bidirectional (driver is determined by CLK_DIR pin)


CLK_DIR Determines the driver for CLK[2..3]_BIDIR. GND (or floating) if the mezzanine module is the driver. 3P3V via 10k pull-up resistor if the carrier card drives the clock signals. Connection is made on the mezzanine module.


GBTCLK[0..1]_M2C_P,
GBTCLK[0..1]_M2C_N		 Clock signals for multi-gigabit transceiver data pairs (GBTCLK1_x only for HPC)


DP[0..9]_M2C_P,
DP[0..9]_M2C_N		 multi-gigabit transceiver data pairs (one is mandatory for LPC, 10 in total with HPC)


DP[0..9]_C2M_P,
DP[0..9]_C2M_N		 multi-gigabit transceiver data pairs (one is mandatory for LPC, 10 in total with HPC)


GA[0..1] Geographical address of the module (can be used for adressing on I2C bus). These pins are driven by the carrier card.


VREF_A_M2C Reference voltage for signaling standard of bank A (LAxx and HAxx). Can be left floating, if not required.


VREF_B_M2C Reference voltage for signaling standard of bank B (HBxx). Can be left floating, if not required.


VIO_B_M2C This voltage is sourced by the mezzanine module which supports the HB bus. It is used to power the IO Bank of the FPGA.


3P3VAUX 3.3 V auxiliary power supply (max. 20 mA, max. 150 uF cap. load).


VADJ Adjustable voltage level (0 .. 3.3 V) from the carrier to the mezzanine card (max. 4 A, max. 1000 uF cap. load).


3P3V 3.3 V power from the carrier to the mezzanine card (max. 3 A, max. 1000 uF cap. load).


12P0V 12 V power from the carrier to the mezzanine card (max. 1 A, max. 1000 uF cap. load).


TRST_L JTAG Reset


TCK JTAG Clock


TMS JTAG Mode Select


TDI JTAG Data In, if JTAG chain is not used by mezzanine card, short TDI and TDO.


TDO JTAG Data Out, if JTAG chain is not used by mezzanine card, short TDI and TDO.


PRSNT_M2C_L Present signal. Indicates that a mezzanine module is attached to the carrier. Low active (tie to GND on FMC)


PG_C2M Active high power good signal. High indicates that VADJ, 12P0V, and 3P3V are within tolerance.


PG_M2C Active high power good signal. High indicates that VIO_B_M2C, VREF_A_M2C, and VREF_B_M2C are within tolerance.


SCL I2C serial clock. Interface can support Intelligent Platform Management Interface (IPMI) commands.


SDA I2C serial data. Interface can support Intelligent Platform Management Interface (IPMI) commands.


RES[0..1] Reserved, left floating


GND Signal ground


_M2C_ Mezzanine-to-Carrier, signal is driven by the mezzanine module and received by the carrier card


_C2M_ Carrier-to-Mezzanine, signal is driven by the carrier card and received by the mezzanine module
