Recently, the domestic four-channel Gigabit Ethernet (GE) transceiver chip YT8614H and eight-port GE transceiver chip YT8618H independently developed by Motorcomm were officially released. Tested by authoritative organizations, the two products feature excellent performance in stability, compatibility and various electrical metrics compared with similar products in the market. The two Ethernet PHY chips are mainly used in multi-port switches and data centers and will make their debut at the Munich Electronics Show in Shanghai on July 3. They are expected to be put into mass production in August 2020.

Motorcomm's core R&D team has successfully launched these two Ethernet PHY chips in June 2020 after repeated research and testing. The whole process of industrial chain including the design, production, manufacturing, packaging, testing and support of chip products are all controlled by Motorcomm, which means that Motorcomm can provide customized design services according to users' requirements and efficient control in the subsequent links.

YT8614H is a four-port GE PHY chip, which supports all physical layer functions of standard Category 5 UTP Ethernet cables and Ethernet fibers, including 1000BASE-T, 100BASE-TX, 10BASE-TE, 100BASE-FX and 1000BASE-X. The uplink interfaces of the chip support SGMII and QSGMII II.

YT8618H is an eight-port GE PHY chip, which supports physical layer functions on Ethernet cables such as 1000BASE-T, 100BASE-TX, and 10BASE-TE, and adapts to two QSGMII uplink interfaces.

In addition, both products have been repeatedly tested and proved to have the following advantages:

High stability

Two chip products, YT8614H and YT8618H, adapt to the latest Ethernet technology, and have passed the large-scale rigorous test of telecom customers, with high stability and reliability.

Rich in functions

Compared with similar products, the two Motorcomm products can provide more functions such as the synchronous Ethernet function, which can realize the clock synchronization of the whole network, prevent the network from being affected by congestion, packet loss, and time delay, and provide a better solution for the construction of switch room in various scenarios, and the EEE function, which can provide lower power consumption for applications in consumer electronics.

Lower power consumption

The power consumption of similar four-port Ethernet products in the domestic market is about 2.4W. After many tests, the power consumption of YT8614H is proved to be about 1.6W, which is one-third less than that of domestic similar products. This can actually reduce the overall system power consumption and save more power costs, which makes YT8618H more competitive than similar products.

Better cost structure

At present, the existing products of domestic manufacturers are mostly for special projects and packaged in BGA, resulting in high costs. YT8614H and YT8618H are packaged in LQFP, and the cost structure is optimized, which further improves the cost performance of the products.

Two chip products, YT8614H and YT8618H, can be applied to multi-port switches and data centers, providing powerful technical supports for the upgrading and optimization of switch rooms in various complex environments. At present, Motorcomm can provide engineering samples, and has reached cooperation intentions with many well-known domestic manufacturers. The two chip products are supposed to be officially put into mass production in August 2020.
