Mindspeed Introduces Industry's First Reclocker with Integrated Cable Driver for the Broadcast Video Market

The new reclocker simplifies system design by offering additional margin through enhanced trace equalization and lower output jitter.

We have leveraged our expertise in signal integrity and low-power design to provide an integrated solution that delivers industry leading performance, density, and power consumption, said Ryan Latchman, vice president of strategic marketing and applications engineering, high-performance analog at Mindspeed. We are excited to roll out innovative solutions that enable the next generation of broadcast of video systems.

Technical Details

The M31285 features two integrated differential 75 ohm cable drivers that each feature programmable swing and pre-emphasis. A standalone reclocker, the M31245 with dual 50 ohm trace drivers with de-emphasis, is also available. Both devices operate at SDI data rates ranging from 270 Mbps to 2.97 Gbps, also support multichannel audio digital interface (MADI) at 125 Mbps, and feature a jitter detector module which measures the jitter present at the input of the reclocker after the signal is equalized.

The M31285 and M31245 both equalize up to 60 inches of trace, integrate Automatic Rate Detect circuitry and internal reference clock, which eliminates the need for an external crystal oscillator reducing complexity and component costs. At 160 mW and 80 mW respectively, the M31285 and M31245 consume significantly less power than existing devices. Both are packaged in a 4x4 mm² 32-pin QFN package providing significant area reduction compared to designs realized with legacy solutions.

Mindspeed will be demonstrating the new reclocker at the 2013 NAB Show at its booth, #N2834 in North Hall of the Las Vegas Convention Center in Las Vegas, Nevada, April 8-11, 2013.
