is a ‘stand-alone system’ which uses the internal MIPS host.
The PNX8526 runs on a single 27 MHz crystal from which all internal and external clocks
are derived by on-chip synthesizers. The PNX8526 boots directly from attached flash
memory or ROM. If desired, custom boot methods can be programmed using the optional
I
The PNX8526 has three digital video inputs that accept digitized analog video (ITU-656),
although only two ITU-656 streams can be processed simultaneously. Two of these inputs,
DV2 and DV3, can also accept scrambled transport streams.

In this table ‘type’ reflects MUX pin function only. A pin may have other ‘type’ capabilities as noted in its
functional group.
These pins are included in the XIO set. Refer to “PNX8526 User Manual, Chapter 8" for additional
functions.
The ICAM1_SETVPP and ICAM1_C8 signals are automatically selected when the ICAM function is
selected. Refer to
