3. Oscillator Sockets

The ML42x platform has two crystal oscillator sockets, each wired for standard
LVTTL-type oscillators. These connect to the FPGA clock pins shown in
oscillator sockets accept both half and full sized oscillators and are powered by 3.3V or the
V
Table 4: OSC Connections

4. Single-Ended SMA Clocks

The ML42x platform has two single-ended clock input SMA connectors that allow
connection to an external function generator. These connect to the FPGA clock pins as
shown in
Table 5: SMA Clock Pin Connections

5. Differential SMA MGT Clocks

The ML42x platform has four pairs of LVDS differential SMA MGT clock inputs as shown
in
