Problems with Printing Graphics in Datasheets

When printing PDF documents to a non-postscript printer (e.g. to PCL printers) some graphics may occur blurry. This is not a problem with the datasheets but with the Acrobat Reader software. A bugfix for the english version of the Acrobat 3.01 Reader is available on Adobe's web pages. Click on the button on the left side for further information.

Sample Circuitry for Universal PCI Boards
(3.3V and 5V)

Nowadays 3.3V environments become more and more common for the PCI bus. As Cologne's single chip solution for ISDN PCI cards HFC-S PCI A can be operated at 5V as well as 3.3V our engineers have developed an universal PCI board sample circuitry for both 3.3V and 5V power supply (auto detection). The sample schematic can be downloaded as PDF-file.

New PCI chip released

Cologne Chip Designs has released the HFC-S PCI A which is compliant to the latest PCI specification 2.2. The new chip is pin to pin compatible to its predecessor HFC-S PCI. The old chip HFC-S PCI is not recommended for new projects.
By end of January the PCI spec. 2.2 has been released by the PCI Special Interest Group (PCI SIG). As Cologne Chip Designs is a member of the PCI SIG we are proud to be one of the first companies world-wide already fully supporting the new PCI 2.2 spec.
The HFC-S PCI A chip is ready for ACPI and supports power management according to the PC 99 standard.

New S/T-Hybrids from APC

A new series of S/T-Hybrid transformer modules with the complete S/T interface circuitry integrated (receiver and transmitter circuitry) for Cologne Chip Designs' ISDN controller chips is now available from APC.
3.3V and 5V versions can be obtained.
For further information please see APC's web pages.

Certified

The HFC-S PCI, the HFC-S+ and HFC-SP have been certified for 3.3V and 5V power supply by the TÜV Laboratories. They are the first ISDN controllers with integrated S/T interface on the world market certified for 3.3V power supply.
Due to their fully digital CMOS architecture the chips can be operated at every voltage between 3.0V and 5.0V. This predestines them to utilization in PCMCIA cards our USB TAs and all low power applications.
