SMTC Short-To-Medium Term Control ), a leading supplier of analog and mixed-signal semiconductors for communications, portable devices, computers, and industrial equipment, today announced the RClamp([R])0524P and RClamp([R])0522P, two new 5V protection devices that are the first solid-state devices to reach 0.3pF in capacitance to meet the needs of High Definition Multimedia Interface (HDMI) 1.3 and other high-speed data lines.
HDMI has been a dramatic success with more than 60 million HDMI-equipped devices shipped in 2006. In June 2006, the new HDMI 1.3 standard was introduced for improved color depth and audio output. HDMI 1.3 doubles the data rate of HDMI signals to 3.4 Gbps per differential pair.
Protecting the data lines at those speeds is a challenge because introducing any significant capacitance on the line will degrade signal integrity. The four-line RClamp0524P and two-line RClamp0522P are TVS TVS Transient Voltage Suppressor

It is applied mainly to acoustic or electromagnetic waves and is expressed as the ratio of power densities. . The ultra low capacitance means that common-mode chokes are not required for impedance compensation in HDMI designs.

The new RClamp devices meet the stringent IEC (International Electrotechnical Commission, Geneva, Switzerland, www.iec.ch) An organization that sets international electrical and electronics standards founded in 1906. It is made up of national committees from over 60 countries.
IEC - International Electrotechnical Commission 61000-4-2 standard for ESD protection (+/-15kV for air, +/-8kV for contact). The devices also meet IEC standards for electrical fast transients (EFT) and for lightning strikes.
Both devices come in special SLP-style packages with an ultra thin design that reduces trace discontinuities. The package is leadless to reduce stubs stubs

The devices also feature a 0.5mm lead pitch so that the differential traces can be tightly coupled for good common-mode noise rejection. These features, combined with 0.3pF capacitance, mean the devices can be used on two-, four- or six-layer boards without added trace compensation, eliminating "guesswork" in the layout.
Semtech also announced that Silicon Image, a leader in interconnect semiconductors for the global PC/display, consumer electronics and storage markets, is evaluating the new RClamp0524P for its HDMI 1.3 reference designs. "Silicon Image prefers to use TVS devices in our reference designs. While technologies such as polymers, varistors and BAV BAV Bavaria

"Semtech TVS protection devices are used on Silicon Image HDMI reference designs due to their excellent clamping and signal integrity characteristics."
"The whole purpose of HDMI 1.3 is to give consumers a better viewing and listening experience, and the RClamp0524P chips are the first TVS devices that give these systems the level of protection they need without impacting signal integrity," said Tom Dugan, Semtech's Director of Protection Products. "The capacitance of these devices is half of the industry norm for TVS arrays, and is a significant achievement for the Semtech team. I would go so far as to say that this has the potential to be the protection industry's biggest innovation this year."
The RClamp0524P is designed primarily for HDMI applications, where only two devices are needed to protect all of the high-speed data lines coming from an HDMI connector. It is available in a 10-pin SLP (Service Location Protocol) An IETF standard used to announce and discover services such as printers and file shares on an IP network. Apple used SLP prior to Mac OS 10.2, but migrated to its Bonjour technology. SLP is also used in SIP-based IP telephony applications. 2510P8 package measuring 2.5 x 1.0 x 0.58 mm. The small size of the RClamp0522P, which comes in a 6-pin SLP1610P4 package measuring 1.6 x 1.0 x 0.58mm, is designed for portable applications with high-speed displays such as cell phones and personal digital assistants. The devices can also be used to protect MDDI MDDI Mobile Display Digital Interface
