ADVANCED SIGNAL INTEGRITY FEATURES Reclocking is an important function required to maintain overall system robustness. As UHD-SDI infrastructure continues to grow in size and as greater amounts of processing are being integrated into broadcast products, overall system jitter can potentially increase. As a result, controlling overall system jitter is critical to reliable operation. The GS12150 includes programmable trace equalization to compensate for high-frequency losses associated with board level interconnects. It operates without an external frequency reference. Programmable output swing and preemphasis provide flexibility for managing signal integrity of the output signals. Processing devices such as FPGAs can have poor input jitter tolerance (IJT) and frequently require external reclocking to maintain overall system margin. The rapid growth in UHD-SDI infrastructure and the associated higher rates make reclocking mandatory in most applications. Semtech offers a complete family of UHD-SDI reclockers for all data rates. The GS12150 reclocker supports rates up to 11.88Gbps with low-power consumption and is ideal for UHD-SDI applications.

And while this architecture fares well in system jitter performance in certain cases, the added engineering effort in developing (or licensing) and stitching that video processing logic to product specific code ensures a slower time-to-market. Finally, while some FPGA-helper parts integrate a cable driver, the offering lacks an integrated equalizer. Transmitter Leveraging our expertise in signal integrity and our deep understanding of broadcast video technologies, Semtech’s SDI transmitter and SDI receiver offering encapsulates all the analog components (SerDes, VCO, CD, EQ and Reclocker) and digital SMPTE video and audio processing required to transmit and receive SDI video. Integrating all of these components into one package reduces the PCB footprint required to implement SDI transmit/receive, and the solution benefits from Semtech’s superior jitter performance. This optimized, cost-effective and power efficient ASIC implementation allows customers to focus on their unique value-added processing for quicker time-tomarket. Only Semtech offers a solution that scores high for each evaluation parameter. High-End FPGA Virtex 5, Stratix II GX VCXO Receiver SEMTECH’S COMPLETE SOLUTION ARCHITECTURE Integrated Transceiver FPGAs Transmitter Designers have the choice of selecting components from different vendors, but when it comes to designs with SDI transmitters and SDI receivers, they must first choose an architecture. In implementing a design with a SDI transmitter and/or SDI receiver, there are three architectural choices: Semtech’s complete SDI transmitter/ SDI receiver solution architecture, an integratedtransceiver FPGA architecture, and a FPGA-helper architecture. Let’s explore these three options with an assessment of the following key parameters: jitter, power consumption, integration (component/features), time-tomarket, system size, and cost. FPGA-Helper SERDES Complete Solution Transmitter/Receiver Low-End FPGA Spartan 3A, Cyclone III Complete SDI Input EQ+Receiver EQ Receiver Proprietary Customer Logic 11 Complete 11 SDI Output Integrated-transceiver FPGAs typically offer the worst specifications in terms of jitter. Maximum output jitter and input jitter tolerance (IJT) are typically at the limit of the Integrated Transceiver SMPTE standards and, in some cases,FPGAs actually in violation of industry VCXO norms. That isHigh-End why FPGA extra components, namely Virtex 5, Stratix II GX VCXOs and reclockers, are required to get the system SDI Output Proprietary Customer Logic jitter performance to an acceptable level. This CD comes at a EQ Reclocker Digital processing penalty of higher powerSMPTE consumption, system footprint size and cost. Because of all the fine tuning required to get this architecture to work and because of the IP licensing/development required for the digital SMPTE video processing, this architecture unnecessarily prolongs time-to-market. Finally, while FPGAs integrate transceivers, they do not integrate routing components like cable drivers and equalizers.

MULTIPLE STROBES TEMPERATURE SENSORS Eight update enabled strobe pins allow our crosspoint to be partitioned into independently updatable blocks. This is useful in multi-format environments when the switches need to occur at different points in time. Each update strobe can be assigned on a per-output basis, enabling maximum flexibility. Four on-chip temperature sensors monitor the junction temperature of the chip. This enables automated control of fan speed and power down sequences to meet environmental demands for energy conservation. LOW-POWER DATA RATE MARGIN Supporting data rates up to 3.5Gbps means that there is significant margin for video systems operating up to 2.97Gbps. This margin also means the product can be used in Xaui™, DisplayPort™ and HDMI switching applications. When compared to competitive solutions, Semtech crosspoints provide industry leading per channel power consumption with less than 1W consumed in stand-by mode. System power can be reduced further by taking advantage of the crosspoint’s high input sensitivity while using Semtech equalizers configured for minimum output swing levels. FULLY INDEPENDENT INPUT AND OUTPUT CHANNELS FLEXIBLE FOOTPRINT All our crosspoints provide independent input trace equalization and output de-emphasis which can compensate for over 50 inches of PCB trace loss. This provides higher signal integrity and lower jitter in designs utilizing long traces or passive splitting. In addition, with output swing configurable as low as 200mV, system power can be significantly reduced. All Semtech crosspoints are pin compatible, sharing the same control interface and register set. This allows a single platform design to be easily scaled to the necessary switch size with no re-work required in either hardware or software. INPUT SENSITIVITY ON-CHIP PATTERN GENERATORS EYE PATTERN DIAGNOSTICS Independent pattern generators and checkers can be used for testing signal paths on either the input or output side of the system. The pattern checker can be configured to check for bit errors using one of three PRBS patterns or any arbitrary pattern, important for evaluating system performance with video pathological signals. All crosspoint devices can check for bit errors at arbitrary phase offsets from the received data, and jitter margin can be determined by measurement of the horizontal eye opening. To address losses typical in many router architectures, the Semtech crosspoint family provides for high input sensitivity, resulting in additional system margin. In addition, high input sensitivity facilitates better system optimization, including reduced swing on upstream drivers, providing substantial power savings.

GENLOCK CAPABILITY REDUCES JITTER TO MEET SMPTE SPECS GS4900B/GS4901B/GS4910B/GS4911B clock generators can be genlocked to reference with a variable offset. On loss of reference, the video clocks will flywheel to maintain their frequency. The GS4915 ClockCleaner™ will reduce jitter on video clocks of 27, 74.25, 74.25/1.001, 148.5, and 148.5/1.001MHz. Output jitter will typically be 20ps, which will guarantee 3Gbps SDI compliance when used with a SDI transmitter. GENERATES MULTIPLE CLOCKS Three video clocks (two single-ended and one differential), three single-ended audio clocks, and eight single-ended configurable timing signals can be generated. Video clocks up to 165MHz can be produced in order to support up to 3Gbps SDI and UXGA. In addition, the GS4911B features crosslocking capability where HD timing can be generated from an SD reference, increasing design flexibility. FLEXIBLE I/O FREQUENCIES AND LEVELS SD (27MHz) and HD (74.25, 74.25/1.001, 148.5, and 148.5/ 1.001MHz) frequencies can be input and output from the GS4915. The chip also has single-ended and differential inputs and outputs to facilitate interfacing with a variety of chips. FREQUENCY DOUBLER TO MEET 3Gbps SDI REQUIREMENTS INPUT STANDARD DETECTION By supplying the clock generator with HSync, VSync and FSync, the chip will determine if it matches one of 36 video or 16 graphics standards and will report the detected standard. Detected Standard Standard Detection HSync VSync FSync Timing Signal Generation Video Clock Generation & Timing Offset If the input clock frequency is 74.25 or 74.25/1.001MHz, the GS4915 can double the output, providing a low jitter 148.5 or 148.5/1.001MHz output clock which can be used for HD-SDI and 3Gbps SDI applications.
