The Layerscape Access LA12xx family of programmable baseband processors delivers high-performance digital signal processing capabilities, performance scalability and application flexibility for 5G sub-6 GHz and mmWave Fixed Wireless Access equipment such as Integrated Small Cells, O-RAN Distributed Unit and Radio Unit and Customer Premises Equipment (CPE). It can be also used in proprietary wireless applications such as defense and civilian radio systems and non-terrestrial networks (NTN).

The family is equipped with a unique combination of:

High performance Vector Signal Processing Accelerators (VSPA)
Forward Error Correction Accelerator (FECA)
Integrated data converting subsystem (ADC/DAC)

Software Support

NXP provides CodeWarrior, the Integrated Development Environment associated with Layerscape Access and many other NXP devices. Included in this environment is a multi-generational, mature compiler as well as access to a rich suite of existing software / signal processing libraries, examples and training material.

A broad ecosystem and comprehensive development platform support is essential to ease development and speed time to market for a commercial grade 3GPP Stacks. All L1 and L2/+ software stack is available from NXP and/or partners depending on the device category and other requirements.

Hardware Tools

Customers can implement and develop their applications with LA12xx evaluation hardware. The LA12xx Evaluation Board is a combination of NXP LX2160 multicore Arm® processor as host and LA12xx modem as baseband for 5G-NR Fixed Wireless applications. The boards come with pre-loaded board support package (BSP) based on a standard Linux kernel.
