4. Oscillator Sockets
The ML32 x platform has two crystal oscillator sockets, each wired for standard
LVTTL-type oscillators. These connect to the FPGA clock pins as shown in Table 4 . The
oscillator sockets accept both half- and full-sized oscillators and are powered by 3.3V or the
VCCO 2.5V power supply.
5. Single-Ended SMA Clocks
The ML32 x platform has two SMA clock inputs that allow connection to an external
function generator. These connect to the FPGA clock pins as shown in Table 5 .
