Overview  \nThe V1401 encodes four stereo pairs of digital audio (8 channels, both left and right justified 16, 18, 20, 22 and 24-bit data formats are supported) and four IO data bits, producing a single data stream suitable for transmission according to the industry-standard ADAT Optical protocol. It is applied in digital mixing boards, signal processors and sound reinforcement products, etc. V1401 features are:  \n• Compatible with ADAT Type I (16-bit) and II (20-bit) formats  \n• 4 stereo pairs as inputs using standard DAC formats  \n• Both left and right justified 16, 18, 20, 22 and 24-bit data formats are supported  \n• 4 IO data inputs to transmit time-code, MIDI data, etc.  \n• Internal PLL generates all required clocks with a word clock input  \n• Package: SOP20  \n2. Block Diagram and Pin Description  \n2.1 Block DiagramF  \nV1401  \n2.2 Block Description  \nThe V1401 Optical Audio Data Generator interface encodes four stereo pairs of digital audio (8 channels) and four IO data bits, produces a single data stream in the ADAT Optical format. This data stream can be transmitted on the optical transmitters to the corresponding optical receiver interface.  \nThe internal PLL locks to the rising edge of WDCLK and realizes 256 multiple of frequency. Then the sample clocks of input data and control signals needed are derived from the output of PLL by the timing control circuitry. These necessary high frequency clocks and timing signals are used to control the sample and latch circuitry and parallel to serial circuitry. Four stereo pairs of digital audio (8 channels) and four IO data bits are encoded to a serial data stream with all data information through these circuits. No Return Zero Inverse (NRZI) encoding of this data stream is realized through output encode circuitry. Finally, the device outputs a data stream in the ADAT Optical format which is suitable for far distance optical transmission.  \nThe specific input format of the digital audio data to be used is selected by the format pins CODE3 to CODE0, both left and right justified 16, 18, 20, 22 and 24-bit data formats are supported. The internal timing control circuitry will provide corresponding sample clocks and control signals to sample and latch circuitry, thus encoding of digital audio with different data formats is realized.  \n2.2.1 Input data formats selection  \nBoth left and right justified 16, 18, 20, 22 and 24-bit data formats are supported in V1401. These formats allow it to match with different devices, and get a flexible application in systems compatible with ADAT protocol. Besides, the device can operate in parallel with many standard DACs.  \nThe specific input format (for IN1/2~IN7/8) to be used is selected by the format pins CODE3 to CODE0. These data input formats are outlined in following table.  \n\n| CODE [3:0] | Input Formats (for IN1/2~IN7/8) |\n| --- | --- |\n| 0000 | 16-bit right justified |\n| 0001 | 18-bit right justified |\n| 0010 | 20-bit right justified |\n| 0011 | 22-bit right justified |\n| 0100 | 16-bit left justified |\n| 0101 | 18-bit left justified |\n| 0110 | 20-bit left justified |\n| 0111 | 22-bit left justified |\n| 1000 | Reserved |\n| 1001 | Reserved |\n| 1010 | Reserved |\n| 1011 | Reserved |\n| 1100 | 24-bit right justified |\n| 1101 | 24-bit left justified |\n| 1110 | Reserved |\n| 1111 | Mute: the digital audio data is screened |\n\nWith the use of the WDCLKNEG input, the user may choose the phase of the word clock to apply to the device. When WDCLKNEG is low, V1401 will expect the rising edge of WDCLK to signal a new period. When WDCLKNEG is high, V1401 will expect the falling edge of WDCLK to signal a new period. In both cases, the first sample data received is the odd numbered (left) channel, and the second is the even numbered (right) channel. Different input formats are shown in following figures.  \nV1401  \nWDCLKNEG=0  \nWDCLK  \nIN1/2~IN7/8  \nWDCLKNEG=1  \nWDCLK  \nIN1/2~IN7/8  \n1/Fs  \nLeft Channe","cbCairGkN3WFFoHf","https://ap.wps.com/l/cbCairGkN3WFFoHf","pdf",1481446,"English","# Overview\n## Block Diagram and Pin Description\n## Block Description\n### Input data formats selection\n### ADAT Optical Data Stream\n## Reset circuitry\n## Internal PLL","[{\"question\":\"What does V1401 encode and output in ADAT Optical format?\",\"answer\":\"V1401 encodes four stereo pairs of digital audio (8 channels) and four IO data bits into a single serial data stream in the ADAT Optical format for optical transmission.\"},{\"question\":\"How are audio input formats selected on V1401?\",\"answer\":\"Audio input format selection is controlled by CODE3 to CODE0, which choose among 16/18/20/22/24-bit left- or right-justified formats, including a mute option.\"},{\"question\":\"How does the internal PLL work and generate clocks?\",\"answer\":\"The internal PLL locks to the rising edge of WDCLK, multiplies the frequency by 256, and derives the necessary sample clocks and timing control signals used to sample/latch data and drive the encoding circuitry.\"}]","ADAT Optical Audio Data Generator and Encoder - V1401 | PDF"]
