Mindspeed intros low-power signal integrity solution for broadcast video apps

IBC 2009, NEWPORT BEACH, USA: Mindspeed Technologies Inc., a leading supplier of semiconductor solutions for network infrastructure applications, has introduced a dual-channel backplane equalizer and re-driver that is optimized for serial digital interface (SDI) applications in the broadcast video market.

With excellent jitter performance and less than 50mW typical power consumption per channel, the device joins Mindspeed’s low-power SDI product family, including the industry’s first low-power multi-channel/rate chipset with dual-cable equalizer and driver, and quad video reclocker.

Each independent channel in Mindspeed’s M21004 backplane equalizer and re-driver features pin-configurable input equalization and output de-emphasis, enabling it to compensate for losses accumulated across long traces and connectors. In addition, an integrated, non-blocking 2x2 crosspoint switch provides the functions of signal splitting, switching, and multiplexing within the same small form factor.

“Mindspeed has been dedicated to providing solutions for the signal-integrity challenges faced by broadcast video equipment designers,” said Kurt Busch, senior vice president and general manager of Mindspeed’s high-performance analog products group. “With this device, we enable system designers to achieve robust operation at data rates up to 3Gbps, without the use of costly connectors, material and components.”

Manufactured in low-voltage complementary metal-oxide-semiconductor (CMOS), the M21004 device may be powered from a 1.2V supply for the lowest power consumption, while an integrated regulator allows it to be powered from any supply up to 3.3V for ultimate flexibility.

The low-power device features universal direct coupled (DC) input interfaces, as well as independent input and output supply rails, eliminating the need for additional level shifters on the board. Integrated termination resistors provide further savings in valuable board real estate.
