... Although the device can operate with low f used at only these low frequencies, the CXD2570Q is recommended that is pin-compatible with the CXD2555Q. CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied ...

... When using the XCS2555Q in multiple units pair with DA converters such as the CXD2558M, one of these CXD2555Qs should be in the master mode to serve as the source of clocks LRCK and BCK. The other CXD2555Qs are used in the slave mode, with their clocks LRCK and BCK supplied by the master CXD2555Q ...
