In 1994 a group of German electronic engineers founded COLOGNE CHIP Designs with the objective to develop and manufacture the ASICs required for ISDN equipment.
COLOGNE CHIP develops and manufactures ISDN controller ICs for Basic Rate and Primary Rate Access. Board with HFC-S mini.
The company offers highly integrated HDLC controller and ISDN transceiver chips for a broad variety of ISDN applications, such as PABX, digital phones, VoIP gateways, Integrated Access Devices (IAD) and POS terminals. For PC add-on cards there are single-chip solutions available.
All chips are built in pure digital CMOS architecture which leads to utmost stable quality and makes high functional integration possible – at excellent prices. By patented technology, the line interfaces for ISDN S/T or E1 are part of the chips, too.
Being a company of innovation ever since, COLOGNE CHIP holds a significant number of patents and registered intellectual properties – besides ISDN also in CODEC technology (ADC/DAC) and other fields. As a consequence the company does not only supply its standard products, but increasingly supports customer ASIC projects by granting licenses of intellectual properties (IP blocks).
Nowadays, the ISDN transceivers of COLOGNE CHIP are demanded in growing quantities for Residential Gateways for broadband access via xDSL, cable, 4G or fiber: So the company contributes to the migration from traditional PSTN to IP-based Next Generation Networks, underlining its technological leadership in the ISDN market.
