Carrier Cards

Tews' TCP261 is a standard 6U CompactPCI carrier that provides front I/O and rear I/O for up to two single-width PMC modules.

The 32-bit and 64-bit PCI accesses are supported on PCI bus with PCI frequency 33MHz and also 66MHz. The transparent Intel PCI-to-PCI bridge 21154 provides the real connection between primary CompactPCI bus and the two secondary PMC slots. The bridge controls all PCI accesses, data bus width and in each case the frequency for a PMC access to one of the connected modules.

The TCP261 supports standard PMC front I/O and for both PMC slots CompactPCI rear I/O. The PMC slot 2 is connected directly to the CompactPCI connector J4 and J3. The PMC slot 1 is connected directly to the CompactPCI connector J3.

Capability of hot swapping is realized by a hot-swap controller for the TCP261. The hot-swap controller and the PCI-to-PCI bridge are controlling the installation and reinstallation process of the TCP261 without power down the system.

The TCP261 carrier complies with the PICMG 2.0 Revision 3.0 CompactPCI specification.
