Overview

The CMS0035 DVB-Satellite Modulator is an integrated core featuring our DVB-S/-DSNG modulator (CMS0010) and DVB-S2/-S2X modulator (CMS0025) cores. The CMS0035 core provides all the functionality required to address the requirements of the ETSI forward-link satellite Standards EN 300 421 (DVB-S), EN 301 210 (DSNG), EN 302 307-1 (DVB-S2) and EN 302 307-2 (DVB S2X), with additional support for DVB-S2X VLSNR operation. The core can operate in a constant coding-and-modulation (CCM) mode for all Standards and in the enhanced variable-coding-and modulation (VCM) and adaptive-coding-and modulation (ACM) modes provided by DVB-S2 and DVB-S2X.

The core provides all the necessary processing steps to modulate a single transport stream (or baseband frame in the case of DVB-S2/-S2X) into a complex I/Q signal for input to a pair of DACs, or an interpolating DAC device such as the AD9857. Optionally, the output can be selected as an IF to supply a single DAC.

The active DVB-S/-DSNG FEC code-rate is controlled via a control register.

The active DVB-S2/-S2X FEC code-rate and frame size are defined by the mod_cod and type parameters associated with each TS packet (or input-frame) and are controlled through the external mode control ports, or optionally from a control register for CCM applications.

The design has been optimised to provide excellent performance in FPGA devices.

Provider

Commsonic Ltd
HQ: UK
Commsonic is a design services company specialising in the development of ASIC, FPGA, DSP and board-level sub-systems for applications in wireless and wireline communications.

Our expertise is primarily in the gate- and power-efficient implementation of physical-layer (PHY) functions such as: modulation, demodulation, equalisation and channel coding but our experience encompasses all of the major elements of a modern baseband 'core' including the medium access control (MAC), voiceband DSP, mixed-signal interfaces, and embedded Cpu and software.

Our services are provided on a turnkey basis or as part of a support package attached to our licenced IP or tool products.

Commsonic's customers are typically semiconductor vendors and manufacturers of communications equipment that require leading-edge, Standards-based or proprietary PHY solutions but lack the internal resources or skills necessary to deliver projects against aggressive deadlines.

Three Major Inflection Points for Sourcing Bluetooth Intellectual Property

Synopsys is now shipping support for Bluetooth® 5.4, the latest specification from the Bluetooth SIG (Special Interest Group). The enhancements in Bluetooth 5.4 will open additional markets and use cases. This is one of the many inflection points in the Bluetooth Low Energy market that will be discussed in this paper.

Part 2: Opening the 5G Radio Interface

Carriers are now deploying 5G across the globe driven by the need to keep up with relentless mobile data growth. 5G New Radio (NR) operates at higher frequencies to increase bandwidth, but at the expense of range. There will therefore be a need for a much larger number of 5G RUs to provide the same coverage. The availability of cost-effective, reliable and open 5G radio units is therefore critical.

An Integrated, Tunable RF Filter: an Enabler for Reconfigurable Front-Ends

This paper presents the design and performance of a key RF circuit necessary for the realization of a reconfigurable, integrated RF front-end: a tunable frequency, selectable bandwidth, on-chip, “SAW replacement” filter. The on-die tunable filter presented here has a tunable center frequency up to 1 GHz, a selectable bandwidth up to 40 MHz, and an adjacent channel rejection down to 60 dB.

Design considerations for integrated CMOS receivers

To meet the demands for the multi-band, multi-mode wireless standards in the current market, a highly integrated wireless receiver (RX) is desired. CMOS technology has become the technology of choice for the integrated receiver design.

Silicon IP for Programmable Baseband Processing

An efficient IP reuse strategy relies on IP blocks with wide applicability. That makes generic blocks, such as programmable processors preferable. However, in many applications such as handheld wireless terminals, additional silicon area and power consumption compared to fixed function solutions can not be accepted.
