Description  
Compatible to HMVIP and H.100 specifications  
Automatic frame offset delay measurement  
Per-stream frame delay offset programming  
Per-channel message mode  
The MT90863 Rate Conversion Switch provides  
switching capacities of 2,048 × 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 64kb/s  
channels per frame with data rates of 2.048Mb/s,  
4.096Mb/s and 8.192Mb/s respectively.  
Per-channel direction control  
Per-channel high impedance output control  
Non-multiplexed microprocessor interface  
Connection memory block programming  
3.3V local I/O with 5V tolerant inputs and  
TTL-compatible outputs  
The MT90863 also offers a sub-rate switching  
configuration which allows 2-bit wide 16kb/s data  
channels to be switched within the device.  
IEEE-1149.1 (JTAG) Test Port  
Applications  
The device has features (such as: message mode;  
input and output offset delay; direction control; and,  
Medium and large switching platforms  
high  
impedance  
output  
control)  
that  
are  
CTI application  
programmable on per-stream or per-channel basis.
