Semtech Extends its Low Capacitance Platform with RClamp®7534P to Protect Next Generation HDMI 2.0 Interface
Semtech’s RClamp7534P TVS features ultra-low capacitance to protect sensitive Ultra HD (4K) TVs from transient events
Camarillo, California - January 6, 2016 -
Semtech Corporation (Nasdaq: SMTC), a leading supplier of analog and mixed-signal semiconductors, today announced the RClamp®7534P, a 4-line integrated Transient Voltage Suppression (TVS) array designed to protect emerging high speed HDMI 2.0 interfaces against electrical transient threats. Targeted at the rapidly growing Ultra HD (4K2K) market featuring the new HDMI 2.0 interface, the RClamp7534P is specifically engineered to meet the rigorous signal integrity requirements of HDMI 2.0 as well as deliver robust ESD protection for highly sensitive HDMI 2.0 chipsets.
Traditionally, TVS devices relied on large capacitances to improve clamping performance. However, in next generation applications such as HDMI 2.0, having low capacitance is key to ensuring signal integrity and minimizing bit errors. The RClamp7534P features a typical 0.19pF line-to-ground capacitance and enhanced ESD immunity level (±25kV air discharge and a ±20kV contact discharge).
The RClamp7534P also features an innovative flow-through package that offers a 20 percent PCB space saving over traditional 4-line TVS devices to accommodate space constrained designs while improving overall clamping performance.
“To enable high speed performance, chipmakers are continuously pushing process geometries to smaller form factors, which means new controllers and SoCs are ever more sensitive to ESD transients. In addition, the pluggable nature of these high speed interfaces means they will be more susceptible to failures unless designers make a conscious effort to select the right protection device for their design,” said Rick Hansen, Product Marketing Director for Semtech’s Protection Product Group. “The RClamp7534P not only offers exceptional clamping performance, but also the ultra-low capacitance that provides designers added signal integrity margin, making the product invaluable to systems employing 4K capabilities, such as televisions, media streaming devices, set top boxes and other similar consumer products.”
