The last installment of this two-part series presents the province’s current and upcoming selections of A/V and PC connectors and cable assemblies.
High-end A/ V and computer connectors and cable assemblies are on the agenda of makers in Jiangsu province under efforts to broaden their selections and application base. Companies are boosting the release of HDMI 1.4, DisplayPort 1.2, USB 3.0, IEEE 1394c and SATA III products to match trends for faster data rates in terminal devices.
In the HDMI category, suppliers are leveraging 1.4’s advantages in terms of capability to support 5Gbps, up to 4000x2000 pixels, and sYCC601, Adobe RGB and AdobeYCC601 color spaces. In addition, HDMI 1.4 boasts Ethernet and Audio Return Channel, 3D rendering in all resolutions, and Automotive Connection System. The specification also covers a microconnector for mobile devices, including phones. As such, businesses are optimistic adoption will expand to the PC and automotive sectors from traditional stronghold flat-panel TVs.
DisplayPort 1.2 has 17.28Gbps maximum transmission speed, and enables multiple independent streams, stereoscopic 3D, higher auxiliary channel bandwidth and more color spaces. Makers hope to benefit from the standard’s compatibility with Apple’s Mini DisplayPort connection.
USB 3.0 packs a 4.8Gbps rate, and is expected to hit 10Gbps and even 20Gbps in future. It has a 4V operating voltage and 150mA power. IEEE 1394c allows 800Mbps in Cat 5e cables. SATA III delivers 6Gbps and includes NCQ management function.
At present, the mainstream supply of interconnects in Jiangsu comprises earlier generations. HDMI 1.3 and RCA variants dominate the A/V segment, with SCART and Mini-DIN making up the rest. The major counterparts in the PC sector are USB 2.0, IEEE 1394 and D/D-sub. The other computer-use types manufactured in Jiangsu are DisplayPort, DVI, SATA/eSATA and RJ-45.
Aside from bolstering their product lineups, makers continue to emphasize customization and cosmetic enhancements owing to the relative mature technology.
Suppliers are confident of the line’s sustained growth, which is projected at 10 percent in terms of export volume in the next one or two years. Driving demand is climbing shipments of popular terminal applications, including tablet PCs that are expected to sustain more than 40 percent annual rise in the next five years. Enterprises are eyeing the upswing in deliveries of such electronic products to emerging destinations India, South America and the Middle East.
Changzhou Comp Electronics Co. Ltd expects the increase to exceed 10 percent by year-end and 2013, mainly because of higher requirement from the last two destinations. The supplier has been sending 90 percent of A/V connectors and cable assemblies overseas.
Businesses are also looking to broaden adoption in automotive A/V electronics, which they said will be a hot application in the years ahead.
Overall, China’s connectors and cable assembly industry has been in an upturn based on statistics from the China Electronic Components Association. With a 20 percent share of global sales, the country overtook North America as the second-largest interconnects source in 2010.
