Detailed Description

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.
