The local connected serial inputs and outputs have 32, 64 and 128 64kb/s channels per frame with data rates of 2.048, 4.096 and 8.192Mb/s respectively. The backplane connected serial inputs and outputs have 128 and 256 64kb/s channels per frame with data rates of 8.192 and 16.384Mb/s respectively. The MT90866 also offers a sub-rate switching configuration which allows 2-bit wide 16kb/s or 4-bit wide 32kb/s data channels to be switched within the device. The device has features that are programmable on per-stream or per-channel basis including message mode, input delay offset, output advancement offset, direction control and high impedance output control.
