DESCRIPTION:
The IDT7216 is a high-speed, low-power 16 x 16-bit multiplier, ideal
for fast, real time digital signal processing applications. Utilization of a
modified Booths algorithm and IDT’s high-performance, submicron CMOS
technology, has achieved speeds comparable to bipolar (20ns max.), at 1/
10 the power consumption.
The IDT7216 is ideal for applications requiring high-speed multiplication
such as fast Fourier transform analysis, digital filtering, graphic display
systems, speech synthesis and recognition and in any system requirement
where multiplication speeds of a mini/microcomputer are inadequate.
All input registers, as well as LSP and MSP output registers, use the same
positive edge-triggered D-type flip-flop. In the IDT7216, there are indepen-
dent clocks (CLKX, CLKY, CLKM, CLKL) associated with each of these
registers.
The IDT7216 offers additional flexibility with the FA control and
MSPSEL
functions. The FA control formats the output for two’s complement by shifting
the MSP up one bit and then repeating the sign bit in the MSB of the LSP.
The
MSPSEL low selects the MSP to be available at the product output port,
while a high selects the LSP to be available. Keeping this pin low will ensure
compatibility with the TRW MPY016H.
FEATURES:
16 x 16 parallel multiplier with double precision product
16ns clocked multiply time
Low power consumption: 120mA
Produced with advanced submicron CMOS high performance
technology
IDT7216L is pin- and function compatible with TRW MPY016H/K
and AMD Am29516
Configured for easy array expansion
User-controlled option for transparent output register mode
Round control for rounding the MSP
Input and output directly TTL-compatible
Three-state output
Available in PLCC
Speeds available: L16/20/25/35/45/55/65
