Overview
As gaming application needs real time, quick and fast reaction, user would like to have low latency solution for gaming application. Existing BT solution has higher latency. Also power consumption is critical in the design with limited battery capacity.
NXP’s gaming headset solution combined with low latency and lower power consumption than competitors. We provide two platforms. One use KL27 MCU and the other one use LPC5528 MCU as processor. The key different feature between these two MCU platform is the audio resolution support.
KL27 platform supports 48K sampling rate and LPC5528 platform supports USB audio up to 96K sampling rate. We design USB dongle and headset side solution, either module or Arduino interface H/W design. Also PMIC is important in the headset side. NXP can provide MCU, BLE and PMIC for this application.
