Mindspeed Technologies, Inc. (NASDAQ: MSPD), the leader in system–on-chip (SoC) solutions for small cells, today announced the third generation of its Transcede® family of baseband processors. The first products of the new generation are the T4400, which extends the product family to address higher capacity metrocell class small cells, and the T3400 for premium enterprise and lower performance metrocells. The Mindspeed® small cell SoC portfolio now covers the complete range of small cells, from cost-effective residential femtocells through low-cost enterprise, high performance enterprise and picocell through to high-performance metrocells. The new products support dual-mode capability, allowing both LTE (either LTE FDD or TD-LTE) as well as simultaneous 3G (either HSPA or TD-SCDMA), leveraging the former Picochip technology. Significantly, they support 3GPP Release 10 (LTE-A) and have a roadmap to Release 12 (LTE-B).
The third generation of the Transcede family is fabricated in 28nm process and provides four times the baseband performance of the 32nm second-generation Transcede devices (T2200 and T3300), which are shipping today for carrier deployment. These products are ideally suited for full featured smart enterprise small cells and metrocells serving high-capacity usage in dense urban areas and rural deployments. The T3400 supports 200 LTE users and 64 HSPA+ users, with 2x2MIMO with 40MHz channels. The higher performing T4400 supports up to 400 plus users in LTE mode and 128 users in HSPA+ mode, and is capable of 4x4 MIMO with 80MHz channels. For HSPA+ the devices support dual-carrier (DC) and Soft Handover (SHO). The new Transcede family is architected to support not just the current LTE-A standards, including carrier aggregation, but the upcoming standards, LTE-B / LTE-HI with even higher data rates and more complex signal processing. LTE-Advanced (LTE-A) describes Release 10 and 11 while the terms LTE-B and LTE-HI (LTE-Hotspot/Indoor) have both been used about Releases 12 and 13.
