MT90863 Description
    The MT90863 Rate Conversion Switch provides switching capacities of 2,048 x 512 channels between backplane and local streams, and 512 x 512 channels for local streams. The connected serial inputs and outputs may have 32, 64 and 128 64 kbps channels per frame with data rates of 2.048, 4.096 and 8.192 Mbps respectively. The MT90863 also offers a sub-rate switching configuration which allows 2-bit wide 16 kbps data channels to be switched within the device. The device has features (such as: message mode; input and output offset delay; direction control; and, high impedance output control) that are programmable on per-stream or per-channel basis.
