TMC2249AKEC1 Description
The TMC2249A is a high-speed digital arithmetic circuitconsisting of two 12-bit multipliers, an adder and a cascade-able accumulator. All four multiplier inputs are simulta-neously accessible to the user, and each includes a user-programmable pipeline delay of up to 16 clocks in length.The 24-bit adder/subtractor is followed by an accumulatorand 16-bit input port which allows the user to cascade multi-ple TMC2249As. A new 16-bit accumulated output is avail-able every clock, up to the maximum rate of 60 MHz. Allinputs and outputs are registered except the three-state out-put enable, and all are TTL compatible.
TMC2249AKEC1 Applications
• Video switching
•Image mixing
• Digital signal modulation
• Complex frequency synthesis
• Digital filtering
• Complex arithmetic functionsThe TMC2249A utilizes a pipelined, bus-oriented structureoffering significant flexibility. Input register clock enablesand programmable input data pipeline delays on each portoffer an adaptable input structure for high-speed digitalsystems. Following the multipliers, the user may performaddition or subtraction of either product, arithmetic roundingto 16 bits, and accumulation and summation of products with acascading input. The output port allows access to all 24 bits ofthe internal accumulator by switching between overlappingleast and most-significant 16-bit words, and a three-state out-put enable simplifies connection to an external system bus.The TMC2249A has numerous applications in digital pro-cessing algorithms, from executing simple image mixing andswitching, to performing complex arithmetic functions andcomplex waveform synthesis. FIR filters, digital quadraturemixers and modulators, and vector arithmetic functions mayalso be implemented with this device.Fabricated in a submicron CMOS process, the TMC2249Aoperates at guaranteed clock rates of up to 60 MHz over thefull temperature and supply voltage ranges. It is pin- andfunction-compatible with Fairchild’s TMC2249, while pro-viding higher speed operation and lower power dissipation. Itis available in a 120 pin Ceramic Pin Grid Array (CPGA),120 pin Plastic Pin Grid Array (PPGA), 120 lead MQFP toPPGA package (MPGA), and a 120 lead Metric Quad Flat-Pack (MQFP).
