Parade Technologies, Ltd. (Taiwan OTC: 4966.TWO) has introduced the availability of two new quad channel linear redrivers to support both 224Gbps and 112Gbps Ethernet applications for server, storage and high performance AI scale-up data center cable use.
Specifications such as IEEE802.DJ and CEI-224G, implement multi-level PAM-4 signaling and demand optimized bandwidth, high linearity, and flat group delay. With industry leading linearity and best possible group delay – particularly when there is line rate adjustment, the PS9524/PS9514 Ethernet Linear Redrivers provide programmable EQ boosts up to 25dB/22dB, while operating from a single 3.3v supply. Key parameters for the HPC/AI datacenter include low power and low latency, making retimed cables more problematic. With its small form factor and low power consumption, the PS9524/PS9514 are optimized to fit existing metal shells of various form factors (including QSFP, QSFP-DD, OSFP, OSFP-XD) without the need for additional heat sink. The advanced linearity allows data centers to trade-off extended cable distance versus thinner cables to reduce routing and system thermal complexity.
“AI data centers are showing growing concerns around the I/O power and latency,” says Jimmy Chiu, Executive VP of Marketing at Parade Technologies. “With industry leading Insertion Loss Deviation, the PS9524/PS9514 LRDs have enhanced linearity to enable clean link equalization across the full signal bandwidth while greatly reducing power and latency”. The PS95xx series of Quad Channel Ethernet Redrivers expands the reach of copper and routing flexibility to meet critical AI scale up needs.
Availability
Sampling now. Both PS9524 and PS9514 redrivers are housed in a 2.7 mm x 5.8 mm, 57-pin WLCSP package for longer cable applications. Typical power for PS9524 is 1W, and PS9514 is 800mW.
