Pericom offers the following solutions
for both PC-based and embedded video surveillance systems:
- Total Timing
Solutions
- Clock IC
- Frequency Control
- Video Switch
- PCI and PCI Express Bridges and Switches
- Go to all PCI Express Products
With the SaRonix-eCera product line, Pericom
offers a total timing and frequency control solution for video surveillance
systems that include crystals, clock generators, and oscillators:
- PI6Cxx
Clock ICs
- SaRonix-eCera 49S series
crystals
- S161X
series crystal clock oscillators (XO)
Pericom provides several video switch
solutions to reduce the number of video decoders needed for multiple
video sources. This saves in both cost and board space.
- Switch between video sources to video decoders
- RGB, S-Video, or composite video signals inputs
- Single-ended 3V and 5V devices
Pericom's Connectivity family includes
enhanced PCI-to-PCI, PCI-X-to-PCI-X, PCIe-to-PCI, and PCIe-to-PCI-X
bridges. Also included are PCIe packet switches. All of these devices
provide PCI, PCI-X, and/or PCIe port expansion for I/O intensive
applications. These devices allow surveillance systems to expand
and accept multiple video sources.
- Permits more devices or "loads" to
be added to the system
- Allows for more slots for adapter cards in
a system
- Allows for multiple devices on a line card
or add-in card
The video capture add-in card (with desktop
PC based on standard Windows OS) is widely used as a control center
for surveillance applications. The video sources are captured with
video decoders from vendors such as Conexant, Alogics, and Philips
among others. All video frame displays and compression/decompression
algorithms are performed by x86 CPUs or MPEG2 chips inside the PC.
In addition to offering desktop and notebook PC solutions, like LAN,
video, analog and USB switches, Pericom offers an array of products
for current generation and next generation PC-based surveillance
systems for increased capabilities and reliabilities.
For high-end surveillance systems, Industrial
PCs (IPC) are widely used as the console for security and display
management. To support more loads, one CPU (with chipset) board
with either a PCIe or PCI-based backplane is a common platform
to support more PCIe or PCI devices. At least one extra PCI-to-PCI
bridge, PCIe-to-PCI bridge, or PCIe packet switch is needed on
board in this application. The diagram below shows the architecture
of a PCI-based backplane.

Another architecture for a surveillance system
is an RISC-based CPU such as ARM or MIPS, and hardware engines like
DSP or ASIC for handling the video capture function and compression/decompression
algorithms. ARM, MIPS, Philip's Tri-Media media processor, and TI's
DSP are popular examples in this market.
