Description  
Mitel’s MT90810 is a Flexible MVIP Interface Circuit  
(FMIC). The MVIP (Multi-Vendor Integration  
Protocol) compliant device provides a complete  
MVIP compliant interface between the MVIP Bus and  
a wide variety of processors, telephony interfaces  
and other circuits. A built-in digital time-slot switch  
provides MVIP enhanced switching between the full  
MVIP Bus and any combination of up to 128 full  
duplex local channels of 64kbps each. An 8 bit  
microprocessor port allows real-time control of  
switching and programming of device configuration.  
On-board clock circuitry, including both analog and  
digital phase-locked loops, supports all MVIP clock  
modes. The local interface supports PCM rates of  
2.048, 4.096 and 8.192Mb/s, as well as parallel DMA  
through the microprocessor port.  
Local serial interface is programmable to  
2.048, 4.096, or 8.192Mb/s with associated  
clock outputs  
Additional control output stream  
Per-channel message mode  
Two independently programmable groups of up  
to 12 framing signals each  
Motorola non-multiplexed or Intel multiplexed/  
non-multiplexed microprocessor interface
