SlimModem Digital Baseband Core

The SlimModem Digital Baseband (DBB) Core is offered as a complete IP transfer package that includes a complete dual mode, 3GPP Release 6 compliant, 2G and 3G physical layer and optional dual mode protocol stack implementation.

Key Features:

• HSPA Category 10 (14.4 Mbps DL) and Category 6 (5.76 Mbps UL)
• Rx Diversity
• EGPRS (EDGE) multi-slot class 12 and DTM class 11/SAIC
• Single-die DBB targeted for 65nm CMOS technology
• DigRF Radio interface (DigRF version 3.09)
• Application Processor (AP) interface support

The SlimModem DBB Core IP is an upgrade to the market-proven SlimChip modem, which achieved PTCRB and GCF certification, including achieving 99.9% completion on ATT ADAPT certification program.  InterDigital modem core IP is shipping in millions of devices, delivering best-in-class performance with industry leading data rates and receiver performance, in a small size, offering low power consumption and reduced costs.

InterDigital also provides comprehensive engineering support (including multiRAT handover) for the efficient integration into multimode 3G devices and LTE/WiMax products for the 4G market.
