SKY76361-32 / SKY76361-52

Cognitive Wireless Gaming Client System on a Chip (SoC)

The SKY76361-32 and SKY76361-52 are ultra-lowpower, high performance wireless gaming SoCs that operate in the 2.4 GHz ISM band. They provide a high dynamic range, uncompressed wireless digital audio/ data link with robust interference rejection and excellent coexistence with other 2.4 GHz applications (such as Wi-Fi® devices).

The SKY76361-32 and SKY76361-52 are clients in the embedded wireless communication system known as UL2X and support multiple OTA usage scenarios with different numbers of channels, audio bandwidth, data bandwidth, and numbers of clients.

The OTA audio link features a low, fixed latency of < 9 ms while rejecting the multitude of possible interference sources in the 2.4 GHz band. The link can provide up to 138 dB dynamic range ratio and up to  40 kHz audio bandwidth. Audio is inherently synchronized between clients in the network with < 1 μs latency difference.

The UL2X wireless communication system also provides a wireless data link for low latency data transport and a special ultra-low latency HID data link (∼ 1 ms) for wireless game controller and gaming peripheral applications.

The SKY76361-32 and SKY76361-52 SoCs are designed to provide a streamlined system solution with minimal external components. It includes digital I/O peripherals, power management, PDM, and I2S audio interfaces. The digital audio interface over I2S supports up to 24-bit, 96 kHz PCM digital audio.

The SKY76361-32 and SKY76361-52 also include a configurable APU to support equalization, dynamic range control, feathering and mixing.
