Chipanalog CA-IS3030T Isolated Interface IC

Chipanalog CA-IS3030T

The CA-IS303x devices are high-performance, dual-channel, isolated low-voltage differential signaling (LVDS) buffers with up to 3.75-kVRMS isolation rating and up to 1.1-Gbps ultra-fast data rate. These devices are compliant with TIA/EIA-644-A LVDS standard and offer all possible unidirectional channel configurations to accommodate any 2-channel isolated LVDS I/O applications. The CA-IS3030 features two channels transferring LVDS signals in one direction; The CA-IS3031 and CA-IS3032 devices have 2 channels with 1 channel in each direction The CA-IS303xT devices feature internal LDO. When operating from 3.3V power supply, the integrated LDO generates 2.5V regulated voltage from 3.3V input for LVDS and isolator circuits. The CA-IS303xT LVDS isolator accepts both 2.5V and 3.3V supplies. When operating from 2.5V power supply, connect VDDx to VINx to bypass internal LDO.
