P15 XMC Connector
SFP+ Connectors
Board Crystal
Board Crystal:
50MHz (U22)
Frequency Stability
: ± 0.00500% or 50ppm
DDR3 Memory
64 Meg x 16-bit
Micron Device MT41J64M16JT-125:G uses a double data
rate architecture.
Five MT41J64M16JT-125:G memory devices (U8, U9, U10, U11 and U14) are
used to form a 72-bit data bus to the T4 ASIC.
The DDR3 is used to store the T4 microprocessor firmware and also for data
buffers and connection information when offload is enabled.
256Kb EEPROM
256Kb (32,768 x 8)
Atmel SPI Serial EEPROM contains hardware
configuration and PCIe configuration information. It also contains the T4
ASIC firmware configuration data.
32Mb Flash
32Mb (4Mb x 8)
Micron M25P32 Serial Flash contains the T4’s internal
microprocessor firmware code.
114 pin Samtec ASP-103614-05 connector complies with ANSI/VITA 42.3-
2006
P15 is the primary XMC connector
8 Gigabit differential pairs are provided for use as 8 lane PCIe Gen 2.0.
System Management (XMC provides hardware definition information read
by the external controller using IPMI commands and I2C serial bus
transactions.)
3.3V power (4 pins at 1A/pin)
Variable power (5V or 12V) (8 pins at 1A/pin)
20 pin TE Connectivity 1888247-1 or equivalent connector complies with
SFF-8083
SFP+ transceiver signals routed directly to the T4 ASIC are capable of SFP+
maximum data rate of 10 Gigabit/sec.
