COM Express C-D Connector
The COM Express C-D connector is a 220-pin connector providing the following features:
•
IDE interface
•
PCI interface
•
PCI Express Graphics (PEG) interface
•
SDVO functionality
IDE Interface
The JMD330 controller provides a fast IDE interface that supports two IDE devices, including IDE hard
drives and ATAPI devices with independent timings. The IDE interface supports PIO IDE transfers up to 16
MB/second, Ultra DMA transfers up to 133 MB/second, and employs DASP (Drive Active Slave Present)
signals.
PCI Interface
The PCI bus complies with PCI specification Rev. 2.3 and provides a 32-bit parallel PCI bus that is capable
of operating at 33MHz.
PCI Express Graphics (PEG)
The Express-CBR supports the implementation of a x8 link for an external high-performance PCI Express
Graphics card. It supports a theoretical bandwidth of up to 4GB/s. Each lane of the PEG Port consists of a
receive and transmit differential signal pair designated from PEG_RX8 (+ and -) to PEG_RX15 (+ and -)
and correspondingly from PEG_TX8 (+ and -) to PEG_TX15 (+ and -).
