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 -).
