CDMA Spread Spectrum Design services

The design team of Sirius Communications combines in-depth know how of telecommunications systems, and more specifically CDMA and W-CDMA systems, with many years of expertise in the fields of advanced ASIC and FPGA design and CAD development. With this background, Sirius Communications develops custom CDMA and W-CDMA spread spectrum chips for customers requesting specific devices for their applications. In this way, OEM builders all over the world get an important competitive advantage by using the best suited component as soon as possible!

Digitalization, a high level of integration, and extreme customization of the modulation and demodulation schemes provide cost-effective, robust and future-proof solutions

The current product range of Sirius Communications consists of components that are useful in a quite broad application domain, thanks to the high flexibility through programmable parameters and modes. Sometimes it is however interesting to have application specific features also on-chip, or to reduce the flexibility in order to reduce the chip die area, and hence the cost.

Especially when high product volumes are projected, or when specialized applications for high-end markets are envisaged, a CDMA chip tailored towards your needs offers a competitive advantage!

Examples of possible custom spread spectrum components include:

cellular W-CDMA transceiver chips (e.g.: UMTS);
spread spectrum transceiver ASICs optimized for low-rate applications such as messaging;
transceiver chips for high-speed wireless communications, such as WLAN and local multimedia-networks;
spread spectrum chips optimized for powerline transmission/reception, e.g. for domotics applications.

Design Service for W-CDMA related chips:

long term expertise in design of spread spectrum chips

expertise in LPC-VQ vocoder and error coding/decoding chip designs

use of low power system-on-chip architecture (patent holding)

expertise in integrating ARM's microcontroller cores on-chip

support for embedding chips by flexible development boards for each chip a custom CDMA development board design

This expertise, combined with our in-depth know how of spread spectrum communications, makes Sirius Communications unique as supplier and developer of spread spectrum components. Contact Sirius Communications to turn your spread spectrum system design problem into a competitive advantage!

From Feasibility to Custom ASIC design:

Sirius Communications offers a spread spectrum design service: this can e.g. include a joint component specification, prototype ASIC development by Sirius Communications, and support from Sirius Communications for prototype system tests.

The production phase and link with the foundry are taken care off by Sirius Communications as well. Sirius Communications is foundry independent, which provides extra flexibility with respect to selection of on-chip macrocells. Sirius Communications has integrated ARM's 32-bit RISC ARM microcontroller on-chip, and closely cooperates with ARM Ltd who is also shareholder of Sirius Communications.

CDMA ASIC with ARM core

Sirius Communications uses a patented modular chip architecture, with as major benefits:

on-chip integration of a high amount of functional blocks (SOC);
low power architecture through the "Inter Process Communication" concept;
integration of hardware and software functions on a single chip;
rapid design trajectory (download this application note) .

The design team of Sirius Communications has a background of designing complete systems on silicon for the European Space Agency, Samsung, Motorola and SAIT Systems.
