HDMI Solution

The SDA-HDMI software package for the SDA family of Serial Data Analyzers provides a concise set of validation/verification and debug tools written in accordance with High Definition Multimedia Interface (HDMI) electrical test specifications. Covered HDMI test modes include Source and Cable Tests covering amplitude-timing, and jitter parameters as well as cable impedance tests.
In addition to standard eye pattern and jitter tests for HDMI, the SDA real-time test equipment platform provides a complete set of amplitude and jitter measurements, as defined in the HDMI specification. This combination of measurements makes SDA-HDMI a cost-effective, compelling HDMI solution.
Additionally, the SDA-HDMI software package takes advantage of all the user-acclaimed test and measurement tools available in LeCroy‧s instruments:

- D350ST-SP, WaveLinkR 4 GHz Bandwidth Probing System,
available in SP (square pins) input or Solder-In (SI) configurations, for a choice between versatility and the highest signal integrity with the lowest probe loading across the entire bandwidth range.
∝Jitter Wizard tool available in ASDA-J Advanced Serial Data Analysis package ensures proper jitter measurement setup, allowing for correlation with other test instruments such as BERT, Sampling oscilloscopes or time interval analyzers (TIAs).

As hardware designers are quick to recognize, measurement results often need to be summarized and tabulated for quick specification verification. SDA-HDMI goes a leap beyond by incorporating a unique application framework, where every experimental result is saved in XML, format directly compatible with most popular data-base applications. A report generation engine interfaces with the underlying MicrosoftR Access-compatible database to facilitate custom text and graphics based reports. Sample applications that stand to benefit the most from the new software framework include,but are not limited to:

- Chipset developers who require comprehensive silicon characterization to define parametric performance and establish device performance capability.

- Device development teams working in parallel development cycles who need to combine, study, and interpret performance data and correlate with prior design runs .

- Manufacturing/Production test environments where key performance parameters are monitored using control charts or other in-process indicators of device performance .

SDA-HDMI provides access to time-domain-reflectometry (TDR) test capabilities available in LeCroy‧s line of Near Real Time oscilloscopes (NRO). The use of SDA-HDMI in conjunction with the deep memory and powerful analysis library of the SDA instrument family simplify greatly the verification process.

Clock recovery circuitry and clock extraction via Phase-Locked Loops (PLLs) is another significant design consideration. The flexible clock recovery options in the SDA allow for the simulation of virtually any real receiver PLL configuration, thus allowing the simulation of ：what if； scenarios. Jitter results can be measured exactly as the receiver would see them.

As hardware designers are quick to recognize, measurement results often need to be summarized and tabulated for quick specification verification. These test results, together with instrument and signal acquisition/test condition setups, create a fully documented record. SDA-HDMI incorporates a multiple-format report generation engine. This test report contains tabulated numerical values for each individual test result including PASS/FAIL and specification limit columns.

Advanced Real-time Jitter and Eye Pattern Analysis

While the SDA instrument family includes the ability to measure jitter and eye patterns in real time, the SDA-HDMI package leverages the Advanced Serial Data Analysis Library (ASDA-J), which provides ultimate control of PLL design, jitter measurement conditions that include detailed Data Dependent Jitter (DDj) breakdown and also bit error rate (BER) analysis. The SDA provides pinpoint accuracy for eye mask violations locator, even in the presence of Spread Spectrum Clock (SSC).
