Raytac Corp. MD85XXP1 User Manual

 

 

1. Description

Raytac’s MD85XXP1 audio module is a cost-effective and low-power solution optimized for 

wireless transmission of high-quality digital audio. We use TI’s CC8520/CC8530 IC (Digital I2S 

I/O) and CC8521/CC8531 (USB full speed I/O) IC which includes a robust built-in wireless 

audio transmission protocol and can control selected external audio devices.

The wireless range is up to 100 meters line of sight with an external PA (TI CC2590). 

Utilizing numerous coexistence mechanisms allows MD85XXP1 to avoid interfering with, or 

being interfered by other 2.4GHz radio systems. Therefore, MD85XXP1 has excellent anti-WiFi 

performance. MD85XXP1 operates autonomously, and can be used with or without an external 

MCU. An external host processor can be connected through SPI and control some aspects of 

its operation.

Combined with the easy-to-use configuration tool and application reference designs, 

MD85XXP1 wireless audio module ensures flexibility, cost-efficiency and a fast time-to-market.
