Award winning semiconductor chips inside award winning product

UK based broadcast test equipment maker PHABRIX Ltd has selected National Semiconductor's 3-Gbps SDI Family devices in its award-winning portable Signal Analyzer.

"We selected National's products based on their raw performance, innovative architecture and outstanding design support," said Philip Adams, managing director of PHABRIX. "Jitter performance is paramount in broadcast video test equipment and National's LMH0340 and LMH0341, 3G-SDI serializer and deserializer deliver the ultra-low output jitter and high input jitter tolerance required for our demanding application. National's unique SerDes architecture enabled us to implement the digital SMPTE video and audio processing in the FPGA instead of on chip. Now, our customers can simply download the latest firmware to update new raster formats or support more channels of embedded audio."

PHABRIX selected the following National Semiconductor products for the SxE triple-rate SDI handheld video test instrument:

1. LMH0340 triple-rate SDI serializer with integrated SMPTE cable driver supports 30 ps output jitter at 3G and HD rates, requires no external voltage-controlled oscillator (VCO) and cleans FPGA PCLK jitter with an integrated LC-based oscillator.

2. LMH0341 SDI deserializer with reclocked serial loop through supports 3G/HD/SD data rates with 0.6 UI minimum input jitter tolerance, requiring no external VCO or reference clock.

Both the above devices have won awards.

3. LMH0384 triple-rate SDI extended reach adaptive cable equalizer supports 140m of cable equalization at 3 Gbps rates and features an auto-sleep mode that reduces power consumption by 87%.
4. National's LMK03000 precision clock conditioner integrates a phase locked loop (PLL) and VCO to clean and distribute ultra-low-noise clock signals throughout the system, with ultra-low 0.8 ps RMS jitter performance.
