Dear IP User,
If your application is in the Cellular field, you will find at Chipidea a wide portfolio of solutions that match your
technical requirements at 180nm, 130nm, 90nm and 65 nm.
We support a large range of functions including Analog Baseband (ABB),
3GDigRF to interface with a separate Cellular RF chip,
Power Management, Audio Codecs, and
USB.

Main features are:
- Highly programmable interfaces supporting different RF chipsets, and multimode
radios (eg. EGPRS and WCDMA);
- Upgradeable capabilities to support 3G-LTE and WiMax
- Compact 10-bit DACs for RF control and 10-bit ADCs with multiplexed inputs for
system monitoring;
- Rx Path based on reconfigurable Sigma-Delta modulator, providing optimized current
consumption for EGPRS and WCDMA modes, saving chip area by re-using the same IP
- Tx Path includes digital interpolation filters, I&Q DACs and voltage or current
output modes;
- Extensive support for multiple communication standards including GSM/EGPRS, CDMA,
TD-SCDMA,WCDMA/UMTS, etc.
- See CI7640tm
for an example of a very compact embedded core solutions; CI7625tg
for a high performance companion die solution; CI3383tn
for a Rx path only core.

Chipidea's DigrRF core is a complete chip-to-chip interface between the RF chip-set and the baseband ICs for cellular
systems. Compliant with 3G DigRF V3.07 specifications, it includes a master interface (digital baseband side) and a slave
interface (RF IC side), with a Controller and a Physical layer (PHY) for a complete, fully integrated link (diagram below).
See CI14112.

USB is the wired interface of choice for mobile cellular applications, by combining power supply and data communication
in the same physical interface.
Chipidea offers a complete solution comprising a family of USB Link Controllers (link to Web Brochure)
and USB Physical layers (link to web brochure) that are silicon proven and USB-IF certified.
See CI12343tn,
the first industry’s USB High Speed PHY with Certification in TSMC65nm.
