Introduction Features
PPC/PMC-8260/DS1 1 - 3
Features
The PPC/PMC-8260/DS1 is a single-size PMC (PCI mezzanine card) module
based on the PowerQUICC II (MPC8260), a versatile microprocessor and periph-
eral controller for communication and networking applications.
Combined with a CompactPCI or VME CPU carrier board, the
PPC/PMC-8260/DS1 is an ideal platform for applications in areas such as Wireless
Infrastructure, Unified Messaging Servers, Enterprise Computer Telephony, Intel-
ligent Peripherals, and Advanced Intelligent Network.
To reduce your software development efforts when enabling communication with a
telecommunication management network, Motorola offers MTP-2, LAPD, Frame
Relay protocol stacks for the operating systems Solaris, VxWorks and Linux.
Revision 1.3 of the PPC/PMC-8260/DS1 provides the following improvements
compared to Revision 1.2:
•
New HiP4 derivate of PowerQUICC II is used which provides an increased
core frequency of 300 MHz and an increased Communication Processor Mod-
ule (CPM) frequency of 200 MHz.
• New bridge: PowerSPAN II (CA91L8260B) with a 32-/64-bit, 33-/66-MHz
PCI interface
• Additional on-board 8 kHz clock source is connected to the T8105. Now,
switching from a line recovered clock source to another clock source, i.e. this
8 kHz clock, is possible.
• Increased SDRAM capacity of 64 MByte
