[time-nuts] BG7TBL FA1 frequency analyzer

[Mark Sims]

Ok, I opened it up... unfortunately my only worthwhile camera has a charger problem... so no nice really photo...                                                                                        

Circuit uses:
a couple of 74LVÇ1G04 chips as input squarers.
Altera MAX-II EPM570T100CSN FPGA
Atmel Mega328 processor
FTDI USB interface
Analog Devices 8028AR dual op amp.
Some 10 pin chip with unreadable markings,
1117 voltage regulator
There are places for ISP and JTAG headers.
