Description
The NA3 HiFi wireless access point is a HiFi network device based on the Celer A1 architecture, utilizing a fully linearly powered ARM platform. All CPU, network, and I/O components utilize a native CelCLK II PLL system for unified clocking. Its wireless portion provides 2.4GHz 802.11n 2x2 wireless access with up to 300Mbps speed, fully satisfying music browsing and control needs. Furthermore, optimized WiFi functionality further enhances local and network music playback quality.
The NA3 leverages the Saier Heart A1 architecture to provide a full LDO power processing platform comprised of 11 LDOs. This platform natively utilizes a unified PLL to supply network/CPU/IO interface clocks, providing a foundation designed entirely for HiFi applications. Building on this foundation, the NA3 enables wireless access point applications, further enhancing sound quality.
Celer A1 architecture uses a fully linear power supply design. All clocks, including CPU, network, and I/O, are uniformly provided by the CelCLK II PLL system. Combined with ARM performance that matches the needs, it is born for various HiFi applications and the ultimate listening experience.
NA3 uses a CelCLK II PLL system with 1Hz locking technology and a 50MHz OCXO as the VCO clock. This is matched with an ideal SMA input interface to achieve high-precision global clock synchronization.
The power supply requirements of pure digital devices are significantly different from those of traditional HiFi devices with analog output interfaces in terms of current and voltage. To this end, Saier Sound has designed a new digital power supply architecture to meet actual needs and provide high-quality playback sound quality.
AP module
The AP module provides a 10/100/1000M network interface and two antenna interfaces. It also provides a CelCLK II PLL system and supports BNC 10MHz clock input.
switch module
Compared with NA3, NA3S has an additional switch module. This module provides two SFP interfaces and two RJ45 interfaces locked to 1000Mbps, and uses the synchronous clock signal from the CelCLK II PLL system of the AP module.
This module provides a special SFP_CTL interface that can be powered on or off via software, thereby physically disconnecting or connecting the device connected to the SFP_CTL interface and significantly affecting the local playback sound.
