Mindspeed Introduces Cable Equalizer With Industry’s Longest Reach And Lowest Output Jitter For Demanding Broadcast Studio Applications
Mindspeed Technologies, Inc. (NASDAQ: MSPD), a leading supplier of semiconductor solutions for network infrastructure applications, today introduced an adaptive equalizer with the longest reach and lowest output jitter for serial digital interface (SDI) applications. The company will be demonstrating the M21544 equalizer at the IBC2012 exhibition in Hall 8, Stand 8.B01 at the RAI Centre in Amsterdam.
The new equalizer joins Mindspeed®’s comprehensive SDI portfolio of equalizers, reclockers, cable drivers and crosspoint switches. It performs adaptive, low-noise, high-gain equalization for 75 ohm coaxial cables at all SDI data rates, supporting greater than 200m at 3Gbps (3G).
The M21544 also features an integrated jitter cleaner that enables it to deliver the lowest output jitter in the industry – less than 0.20 unit intervals (UI) after compensating for 200m of cable at 2.97Gbps. This advancement eliminates the need for stand-alone reclockers at the input of a system, reducing power consumption, complexity and system cost. It also provides additional high-frequency jitter margin, which can be used for intra-system routing and distribution. For applications where it is not required, the optional jitter cleaner can be powered down for even greater power efficiency.
"This equalizer offers the performance, flexibility and power consumption equipment vendors demand for their next generation broadcast video system designs,” said Hasnain Bajwa, senior vice president and general manager, high-performance analog (HPA), at Mindspeed. “Our new equalizer’s capability to extend reach and provide extra system jitter margin will enable broadcasters to maximize utilization of their existing coax based infrastructure.”Technical Details The M21544 is the dual output version of the equalizer, while a single output version, the M21564, is also available. The M21544 is housed in an industry-standard 4x4 mm 2 24-pin quad-flat no-leads (QFN) package, and the M21564 in a 4x4 mm 2 16-pin QFN package. Each differential output features programmable swing as well as de-emphasis, enabling signals to be transmitted across 40 inches of trace. Each equalizer operates using a single 2.5 V supply voltage and features advanced diagnostics capabilities including cable length indication, loss of signal detection and offers power management capabilities. The devices are sampling now.
