Frequently Asked Questions
How many audio channels can the CC8521SRHAR stream wirelessly and at what frequency band?
The CC8521SRHAR supports up to 2 audio channels of wireless digital audio streaming at 2.4GHz using Texas Instruments' PurePath Wireless protocol, delivering uncompressed stereo audio for headsets, speakers, and gaming accessories with lower latency than standard Bluetooth audio codecs.
What USB interface capability does the CC8521SRHAR provide for PC audio accessory designs?
The CC8521SRHAR integrates a USB interface that allows it to connect directly to a PC or laptop host, enabling wireless USB audio dongles and cordless headset adapters to appear as standard USB audio devices without requiring proprietary drivers on Windows or Mac operating systems.
How does the PurePath Wireless protocol on the CC8521SRHAR differ from Bluetooth audio for latency-sensitive applications?
PurePath Wireless on the CC8521SRHAR transmits uncompressed 2-channel PCM audio at 2.4GHz, achieving end-to-end latency well below the typical 40ms to 100ms range of Bluetooth A2DP stereo audio. This makes it suitable for video conferencing headsets and gaming headsets where audio-video synchronization across a 2.4GHz wireless link is critical.
What package does the CC8521SRHAR use and how does it affect thermal management in a wireless audio PCB?
The CC8521SRHAR is housed in a QFN (Quad Flat No-Lead) package with an exposed thermal pad on the underside, enabling efficient heat dissipation through PCB vias to the ground plane. This compact package keeps the 2.4GHz wireless audio module within a small form factor suitable for in-ear or on-ear headset PCB designs.
