This provides a direct connection to chip level interfaces such as I2S and supports all popular serial interface formats including left justified, right justified, and DSP. In addition the option supports TDM or multiple data line configurations for up to 8 channels of audio data. The digital serial capability is essential in R&D for evaluating designs at the circuit board level. It allows direct connectivity to CODECs, DSPs, analog-to-digital and digital-to-analog converters, sample rate converters, and all types of audio processing and interface chips. Users can access and test board-side inputs and outputs to HDMI (when used in conjunction with the APx HDMI option), SPDIF, and other digital interface transmitters and receivers. Pulse voltage, sample rate, word length, data length and the time relationship between clock and data are variable to accommodate a wide range of devices and applications. HDMI RECEIVERS I HDMI TRANSMITTERS A-to-D CONVERTERS I D-to-A CONVERTERS SAMPLE RATE CNVTRS I DIGITAL PROCESSORS Digital Serial and HDMI The Digital Serial option by itself has many applications, but when used in conjunction with the APx HDMI option, truly unique audio test solutions become available. The connectivity between the two options creates a fast and simple solution for HDMI chip developers who need the ability to debug at the circuit board level. It is also the only analyzer in the world that can interface directly to HDMI receiver and transmitter chips, and the only analyzer that can stream high bit rate audio signals such as dts-HD over a multichannel serial interface. Hardware connectivity The transmitter and receiver are interfaced via HD-15 connectors. Each connector breaks out to a master, frame, channel, and bit clock in addition to four data lines. Eight channels of audio data can be carried across the four data lines or the system can be configured for TDM (time division multiplexing) and 8 channels can be carried on a single wire. In addition both the transmitter and receiver signals can be monitored via dedicated, buffered monitor ports. These duplicate the signals at the transmitter or receiver and allow direct monitoring via an external oscilloscope. The APx Digital Serial I/O option includes independent, programmable master clocks for both the transmitter and receiver. This allows the use of two different clocks simultaneously, an important advantage in SRC testing when compared to single-clock serial interface. Digital Serial Key Features 8 channels of simultaneous audio data on TDM or multiple data lines 镕 Dedicated, buffered oscilloscope monitors Built-in support for left or right justified, I2S and DSP formats Օ Automatic rate calculators and active timing diagrams Independent input and output clocks
