* Altera cyclone 1 FPGA: EP1C6Q240C6N
* LMK04821 PLL/clock cleaner
* Serial flash for FPGA configuration: Altera EPCS16
* Socket for Atomic clock CSAC Symmetricom CSAC-SA.45s
* External SDRAM memory
* Microsemi Smartfusion2 SoC M2S-FG484 (ARM CPU)
* VME interface: VME-D[31..0] bidirectional, VME-A[19..0] input only, DTACK output, no BERR, no RETRY/RESP. VME-A[31..20] input only connected only to address decoder FPGA (Altera MAX-something CPLD). This permits all single-word transfer modes, 32-bit DMA (BLT32) and 2eVME DMA (only drives D-lines, but still faster than BLT32). 64-bit DMA (MBLT64) and 2eSST are impossible.
* 10Mbit/s ethernet
* 16 NIM outputs
* no VME interface
* 16 NIM inputs
* dual mode eSATA connector:
* 16 ECL/LVDS inputs compatible with LeCroy 4616 ECL/NIM/ECL converter. (Except: Rev0 boards have an incompatible ECL connector)
** eSATA clock+sync input or
* 16 "red" and 16 "green" LEDs
** USB-A access to ARM CPU serial console via FTDI USB-serial chip
* 1 "VME access" LED
* 24 clock+sync outputs (LVDS) via 6 mini-SAS connectors (SFF-8088)
* 1 RJ-45 high speed serial I/O interface
* 3 dual LEMO connectors: (from top to bottom) ("A" is left, "B" ir right)
** LEMO1A - EXT_SYNC_IN (NIM or TTL sync)
** LEMO1B - EXT_RefClk_IN (NIM or TTL clock)
** LEMO2A - CLOCK_OUT1_NIM (LVDS_CLK7)
** LEMO2B - selected by jumper: CLOCK_OUT2_NIM (LVDS_CLK6) or GPS_1PPS_IN
** LEMO3A - 1PPS_OUT_NIM
** LEMO3B - 10MHz_OUT_NIM
* 4 red and 4 green LEDs
