Overview

The AR35F01A is a digitally coded conversion IP that translates 8-ch (4 stereo channels) of 16-24bit pulse-code modulated (PCM) input data into pulse-width modulated (PWM) outputs. The IP supports three different output schemes, AD, BD and ternary to reduce EMI impact to ambient environment. The PWM outputs can driver off-chip or on-chip P/N MOSFET switches for power-efficient Class D speaker amplifier configuration.

The IP supports standard I2S, left-justified, PCM/DSP digital audio interface (DAI) data format inputs. The DAIs operates at sampling rates ranging from 8KHz to 48KHz. The PWM outputs and features are configurable with on-chip I2C/SPI/AMBA interfaces. It also supports left-channel only, right-channel only mono operation as well as the default stereo operation mode.

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.
