Socionext Introduces New 7nm ADC and DAC for 5G
Direct RF Transmitters and Receivers
Lower Power and Reduced Bill of Materials Supporting Advanced Wireless Systems[Langen/Germany and Yokohama/Japan. February 22, 2023] --- Socionext, a global leader in providing
innovative custom System-on-Chip solutions for wide range of applications including data center and networking,launches a new high-speed Direct RF data converter PHY solution. This is the latest in a series of IP offerings
driving advanced transceiver systems for 3GPP 5GNR/LTE and Wi-Fi network infrastructure in the FR1 and FR2(mmWave with external mixers) bands.
The IPs were developed in TSMC 7nm FinFET (N7) process technology to allow straightforward integration for
32TRX and 64TRX single die solutions and lower power consumption compared to discrete solutions currently
available in the market.
Both ADC and DAC have 12-bit resolution and analog bandwidth up to 7.2GHz. The ADC sampling rate is 24GS/s
and 32GS/s for the DAC, enabling 5GNR FR1 frequency in the first Nyquist data converter frequency range.
This Direct RF IP product family delivers the fullsub-6GHz instantaneous band with an internal
capability to allocate up to 1.6GHz of channel
bandwidthfeaturing

carrieraggregation.

Maximum is 16 channels of 100MHz (FR1) each,or 4 channels of 400MHz (FR2). Furthermore,by using the multiple DDC/DUC available in themacros, it is possible to target low-, mid- andhigh-range bands (e.g., n28, n40 and n78)
simultaneously,

without

dedicated

external

filtering components. The result is a significantly
reduced BOM.

Direct RF test chip and evaluation board are now sampling to select customers. A dedicated application board
with full ADC/DAC and real-time streaming will be available in Q3, 2023”.
SoC Integration
The complete Socionext SoC solution includes a foundation of IP building blocks such as short, medium andlong reach SerDes up to 112/224Gbps, PCIe Gen4/5/6 PHY, eFPGA, DDR and several standards-based, die-todie interconnect technologies for managing data flow across the data infrastructure and chiplets on MCM.
This 7nm data-converter development follows numerous successful 16nm and 28nm designs using Socionextʼshigh-performance ADC and DAC design expertise for networking applications.
Socionext integrates these IPs into other solutions such as 5G CPE, satellite communications, software- definedradio, microwave radio, test & measurement equipment and early 6G research. In a market that requires highlevels of system integration, small package size and low power design, Socionextʼs Solutions are key
differentiators for telecommunication and connectivity customers and for the most demanding environments
utilizing expertise in leading-edge silicon technology and design methodology.
A Paper on the Direct RF ADC (Analog-to-Digital) converter was presented at the ISSCC in San Francisco.
