| MT89L86 Description | The 3.3 V Multiple Rate Digital Switch (MT89L86) is pin compatible with our 5 V MT8986 and retains all of its functionality. This 3.3 V device is designed to provide simultaneous non-blocking connections for up to 256 64 kbps channels or blocking connections for up to 512 64 kbps channels. The serial inputs and outputs may have 32 to 128 64 kbps channels per frame with data rates ranging from 2048 up to 8192 kbps. It also provides per-channel selection between variable and constant throughput delays allowing voice and grouped data channels to be switched without corrupting the data sequence integrity. |
