Socionext 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 full sub-6GHz instantaneous band with an internal capability to allocate up to 1.6GHz of channel bandwidth featuring carrier aggregation. Maximum is 16 channels of 100MHz (FR1) each, or 4 channels of 400MHz (FR2). Furthermore, by using the multiple DDC/DUC available in the macros, it is possible to target low-, mid- and high-range bands (e.g., n28, n40 and n78) simultaneously, without dedicated external filtering components. The result is a significantly reduced BOM.
