6. Zoomed Video Implementation Using PCI1620
Not shown in Figure 3
–
6 is the multiplexing scheme used to route either socket A or socket B ZV source to the
graphics controller. The PCI1620 provides ZVSTAT, ZVSEL0, and ZVSEL1 signals on the multifunction terminals
to switch external bus drivers. Figure 3
–
7 shows an implementation for switching between three ZV streams using
external logic.

7. Zoomed Video Switching Application
Figure 3
–
7 illustrates an implementation using standard three-state bus drivers with active-low output enables.
ZVSEL0 is an active-low output indicating that the socket A ZV mode is enabled, and ZVSEL1 is an active-low output
indicating that socket B ZV is enabled. When both sockets have ZV mode enabled, the PCI1620 by defaults indicates
socket A enabled through ZVSEL0; however, bit 5 (PORT_SEL) in the card control register (see Section 4.40) allows
software to select the socket ZV source priority. Table 3
–
6 illustrates the functionality of the ZV output signals.
