Consumer mobile and edge devices are processing large amounts of data in today’s applications, ranging from video processing, mobile gaming, to AI-based image recognition.  As a result of these advancements, the memory sub-system plays a crucial role in the overall performance.

The TSS LPDDR5X/5/4X/4 PHY utilizes state-of-the-art architecture to maximize timing and voltage margins over process, voltage and temperature variations, while minimizing interruption to data traffic.

Built-in power management logic and advanced PLL design allows aggressive power state management and optimal system power usage.


At the system level, the LPDDR5X/5/4X/4 PHY was designed with minimal package substrate layer and PCB layer count in mind.  This enables the integration of a LPDDR memory sub-system solution in cost sensitive applications, such as consumer edge devices, digital set-top-box and TV, SSD controllers, and application processors.

When integrated together with OPENEDGES' memory controller (OMC), users can expect a high performance total memory subsystem solution that is fully co-validated and ready for deployment at the SoC level.
