MT90866
4,096 x 2,432 Channels Flexible Digital Switch with H.110 Interface
Overview
| The MT90866 Digital Switch provides switching capacities of 4,096 x 2,432 channels between backplane and local streams, 2,432 x 2,432 channels among local streams and 2,048 x 2,048 channels among backplane streams. The local connected serial inputs and outputs have 32, 64 and 128 64 kbps channels per frame with data rates of 2.048, 4.096 and 8.192 Mbps respectively. The backplane connected serial inputs and outputs have 128 and 256 64 kbps channels per frame with data rates of 8.192 and 16.384 Mbps respectively. The MT90866 also offers a sub-rate switching configuration which allows 2-bit wide 16 kbps or 4-bit wide 32 kbps data channels to be switched within the device. The MT90866 is intended for carrier-grade applications that require high bandwidth switching capability. With compliance to the ECTF H.110 specification, it is also suitable for using a compact PCI platform. 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. |
