Based on Silicon Labs’ patented DSPLL® technology, the Si5324 has a fully integrated, digitally programmable loop filter that supports loop bandwidths ranging from 4 Hz to 525 Hz as well as a low phase noise internal VCO. By consuming less than 10% of the overall 3G-SDI jitter budget required in next generation video applications, the Si5324 simplifies design and eases system-level SDI jitter testing. In addition, the Si5324 provides any-rate frequency flexibility by generating virtually any output frequency from 2 kHz to 1.4 GHz from any input frequency ranging from 2 kHz to 710 MHz enabling a single IC design for multi-rate video applications. 3G/SD/ HD-SDI Cable Equalizer Cable Equalizer SDI Deserializer SDI Deserializer Video Processor/ Buffer Pclk, hvf YCbCr Pclk, hvf YCbCr YCbCr Cable Driver Sample Clock HSYNC Sync Input Master Sync Generator SDI Reclocker SDI Reclocker Genlock SDI Serializer Si5338 Clock Generator HD (74.25 MHz) HD (74.1758 MHz) Audio (24.576 MHz) Processor (66.66 MHz) 3G-SDI Reference Clock Si5324 Any-Rate Clock Sync Separator Si554 VCXO Si554 VCXO Si590 XO 3G/SD/ HD-SDI 3G/SD/ HD-SDI Application Example: Production Video Switcher
