Overview  \nThe V1402 decodes a single data stream of the industry-standard ADAT Optical protocol and produces four ADC formats stereo pairs (8 channels) of digital audio suitable for DACs or further processing. With an internal PLL to generate all needed clock signals, the V1402 requires no external clocks in Master Mode, and only word clock (Fs) for proper operation in Slave Mode. The V1402 could be applied in digital mixing boards, signal processors and sound reinforcement products, etc. V1402 features are:  \n• Compatible with ADAT Type I (16 bits), Type II (20 bits) and 24 bits formats  \n• 4 stereo pairs as outputs using standard ADC formats, supports both left and right justified data formats  \n• 4 IO bit outputs to receive timecode, MIDI data, S/Mux etc  \n• Internal PLL to generate all needed clock signals in Mater Mode  \n• Only word clock (Fs) for proper operation in Slave Mode  \n• Word clock input to synchronize outputs to user’s system  \n• Package: SOP24  \n2. Block Diagram and Pin Description  \n2.1 Block Diagram  \n2.2 Block Description  \nThe V1402 is consisted of chip reset, PLL3, PLL1, PLL2, ERR and output circuit. First to reset the chip before it start to work, this will reset all internal counters and state registers to their initial state and disrupt the outputs.  \nHowever, PLL lock to OPIN will not be disturbed. V1402 has two work modes: Master Mode and Slave Mode. In Master Mode, the V1402 requires no external clocks. All outputs are derived from the input ADAT Optical data stream on the OPIN pin and WDCLK is an output signal. In Slave Mode, WDCLK is an input, OUT1/2-7/8, IO0-3, BCLK and SVCO are synchronous to WDCLK. Output circuit transfers the serial data to 24-bit parallel data. 8 channels of 24-bit parallel data are switched to 4 stereo pairs OUTPUT data and 4 IO data. When the V1402 lacks an input or failure to synchronize to data stream occurs, ERR is high and data outputs are muted, but not clock outputs.  \nV1402  \n2.2.1 General Function Descriptions  \nThe V1402 decodes and formats a single data stream of the industry-standard ADAT Optical protocol and produces four ADC formats stereo pairs (8 channels) of digital audio suitable for DACs or further processing. The V1402 supports both ADAT Type I format (16-bit) and the ADAT Type II format (20-bit) with data lengths of up to 24 bits.  \nIO0 is used to receive the ADAT format 32-bit timecode, IO1 is used to receive MIDI data, IO2 is used to receive the S/Mux data indicator and IO3 is reserved and should be tied low.  \n2.2.2 Mode Selection  \nThe V1402 has two working modes, which may be selected by means of the MODE inputs. When in Master Mode, all outputs are derived from the input ADAT Optical data stream on the OPIN pin, and WDCLK is an output. In Slave Mode, OUT1/2-7/8, IO0-3, BCLK and SVCO are synchronous to WDCLK, which is an input. While in Slave mode, WDCLK may be at an arbitrary phase with respect to the incoming samples of OPIN, but if the two frequencies are not identical, samples will be dropped, repeated or garbled. Generally, identical frequencies are achieved by either using DVCO as the source from which WDCLK is generated, or by creating OPIN from a source synchronized to WDCLK.  \n\n| MODE [1:0] | MODE |\n| --- | --- |\n| 00 | Master mode, WDCLK is an output |\n| 01 | Slave mode, WDCLK is an input |\n| 10 | Reserved |\n| 11 | Reserved |\n\n2.2.3 Serial Output Interface  \nThe V1402 has been designed for ease of use and flexibility in systems interfacing with the ADAT protocol.  \nIt supports both left and right justified data formats for ease of integration into existing devices, as well as new devices. These formats allow it to operate in parallel with many standard ADCs. The specific output format to be used is selected by the format pins CODE1 and CODE0 .  \n\n| CODE [1:0] | Format |\n| --- | --- |\n| 00 | Right justified, BCLK falls on WDCLK edge |\n| 01 | Left justified, BCLK rises on WDCLK edg","cbCaiktW8mXeTcZL","https://ap.wps.com/l/cbCaiktW8mXeTcZL","pdf",1647532,"English","# Overview\n# Block Diagram and Pin Description\n## Block Diagram\n## Block Description\n## General Function Descriptions\n## Mode Selection\n## Serial Output Interface\n## Reset Circuitry\n## Inner PLL","[{\"question\":\"What does the V1402 do with the ADAT Optical input signal?\",\"answer\":\"It decodes a single ADAT Optical data stream and produces four ADC-formatted stereo pairs (8 channels) of digital audio suitable for DACs or further processing.\"},{\"question\":\"How do Master Mode and Slave Mode differ in clock requirements?\",\"answer\":\"In Master Mode, V1402 generates required clock signals internally from the ADAT Optical stream and requires no external clocks.
