256 X 128 Channels Flexible MVIP Interface Circuit (FMIC)

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 64 kbps 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.
