4.8 FPGA
The RTM-ATCA-F140 includes a Xilinx XC3S200A-4 FPGA that which performs the following
functions:

Access to control and status signals on SFP, SFP+, and QSFP+

Access to control and status signals on the BCM8727, BCM84754, and BCM84740

Reset handling

Recovery of received clocks from BCM8727 for use as a Synchronous Ethernet reference
clock

Reception of GPS inputs (1PPS, 10MHz, Time-Of-Day)

SPI Flash programmer and multiplexing for BCM8727, BCM84754, and BCM84740
configuration

UART with selectable outputs for the optional GPS receiver (functionality not initially
implemented)
4.8.1 Front-blade Interface
The RTM-ATCA-F140 includes an SPI interface between the front-blade service processor and
the RTM FPGA. There is also an active low interrupt line to the front-blade to request service.
4.8.2 SFP/SFP+/QSFP+ Control and Status
The RTM FPGA provides register access to control the following SFP and SFP+ signals:

SFP TX_DISABLE

SFP RATE_SEL

SFP+ RS0/1 (tied together)
The RTM FPGA provides access to the following SFP, SFP+, and QSFP+ signals:

SFP MOD_ABS

SFP TX_FAULT

SFP LOS
