DIX4192IPFBR Overview
Moreover, the book has an appendix that contains a case study. There is only one mounting type recommended for the product, which is Surface Mount. There is a 48-TQFP case embedded in it. In this case, the device has 4 channels. There are Audio Transceiver functions included in this part for your reference. This device can be applied in both Automotive Audio, Professional Audio and X directions. As far as I know, it is supplied within 1.65V~1.95V days. In this device, the temperature range is -40°C~85°C TA, which is the range of this device. You can find similar parts by searching for the DIX4192 family of parts. The following specifications are related to the device: Differential Output, which can be found here. The chip has 48 pins that are accessible from the outside. Surface Mount mounts it on to the wall. 3.3V-voltage supplies conduct current through the chip. As long as the supply voltage is greater than 1.8V, it can handle it.
