Description

The TMC2249A is a high-speed digital arithmetic circuit

consisting 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 accumulator

and 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. All

inputs and outputs are registered except the three-state out-

put enable, and all are TTL compatible.

The TMC2249A utilizes a pipelined, bus-oriented structure

offering signiﬁcant ﬂexibility. Input register clock enables

and programmable input data pipeline delays on each port

offer an adaptable input structure for high-speed digital

systems. Following the multipliers, the user may perform

addition or subtraction of either product, arithmetic rounding

to 16 bits, and accumulation and summation of products with a

cascading input. The output port allows access to all 24 bits of

the internal accumulator by switching between overlapping

least 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 and

switching, to performing complex arithmetic functions and

complex waveform synthesis. FIR ﬁlters, digital quadrature

mixers and modulators, and vector arithmetic functions may

also be implemented with this device.

Fabricated in a submicron CMOS process, the TMC2249A

operates at guaranteed clock rates of up to 60 MHz over the

full temperature and supply voltage ranges. It is pin- and

function-compatible with Fairchild’s TMC2249, while pro-

viding higher speed operation and lower power dissipation. It

is available in a 120 pin Ceramic Pin Grid Array (CPGA),

120 pin Plastic Pin Grid Array (PPGA), 120 lead MQFP to

PPGA package (MPGA), and a 120 lead Metric Quad Flat-

Pack (MQFP).
