Detailed Description
R
10. Oscillator Sockets
The board has four crystal oscillator sockets, all wired for standard LVTTL-type oscillators.
These sockets connect to the DUT clock pads as shown in Table 4 and Table 5. Onboard
termination resistors can be changed by the user. The oscillator sockets accept both half-
and full-sized oscillators and are powered by the DUT VCCO power supply.
