Product details
Overview
B4860NXE7QUMD from NXP Semiconductors (formerly Freescale) is a 28 nm multi-standard baseband SoC for macrocell LTE/WCDMA base stations, integrating four dual-threaded 64-bit e6500 Power Architecture cores (up to 1.8 GHz), six SC3900FP StarCore DSP cores (up to 1.2 GHz), MAPLE-B3 baseband accelerators, dual 64-bit DDR3/3L controllers, and CPRI v4.2 interfaces - enabling concurrent processing of three 20 MHz LTE sectors in FDD/TDD modes.
For engineers reviewing the B4860NXE7QUMD datasheet, B4860NXE7QUMD pinout, B4860NXE7QUMD application, or B4860NXE7QUMD equivalent, key selection considerations include its 1020-pin FC-PBGA package, hardware-accelerated FEC/FFT/MIMO equalization, DPAA-enabled packet processing, IEEE 1588v2 timing support, and industrial-temperature operation for wireless infrastructure deployment.
Technical Context
The B4860NXE7QUMD implements Layer 1 processing via MAPLE-B3 accelerators (Turbo/Viterbi decode/encode, FFT/iFFT, MIMO MMSE equalization with IRC/SIC/PIC) and SC3900FP FVP cores, while Layer 2/3 and transport functions run on e6500 cores with DPAA (frame/queue/buffer managers) and security accelerators (AES, SHA-2, ZUC, SNOW-3G). CoreNet coherency fabric links all processing elements.
It supports simultaneous multi-standard operation (LTE FDD/TDD Rel.10/11, LTE-Advanced, WCDMA/HSPA+) with hardwired acceleration for PDSCH/PUSCH data paths, WCDMA chip-rate processing, and CRC offload - partitioning compute-intensive PHY tasks between programmable DSPs and fixed-function hardware to optimize power efficiency and spectral throughput.
