DESCRIPTION:
The IDT7216/IDT7217 are high-speed, low-power
16 x 16-bit multipliers 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/IDT7217 are 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 regis-
ters, use the same positive edge-triggered D-type flip-flop. In
the IDT7216, there are independent clocks (CLKX, CLKY,
CLKM, CLKL) associated with each of these registers. The
IDT7217 has only a single clock input (CLK) and three register
enables.
ENX
and
ENY
control the two input registers, while
ENP
controls the entire product.
The IDT7216/IDT7217 offer 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

DESCRIPTION (Cont’d.)
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.
The IDT7216/IDT7217 multipliers are manufactured in
compliance with the latest revision of MIL-STD-883, Class B,
making them ideally suited to applications demanding the
highest level of performance and reliability.

Mode control for each data word. Low designates unsigned data input and high designates two's
complement.
"Round" control for rounding of MSP. When high, 1 is added to the most significant bit of LSP. This
signal is affected by the state of FA pin. When FA = 1 and RND = 1, 1 is added to the 2
-15
bit (P
15
). When
RND = 1 and FA = 0, 1 is added to the 2
-16
bit (P
14
). The RND input is registered. It is clocked on the
rising edge of the logical OR of CLKX and CLKY in the 7216 and on the rising edge of CLK in the 7217.
Rounding always occurs in the positive direction which may introduce a systematic bias.
When low, MSP is output on P
16
- P
31
lines. When high, LSP is output on P
16
- P
31.
Format adjust control. When high, a full 32 bit product is selected. When low, a left shifted 31 bit product
is selected with the sign bit replicated in the LSP. FA is normally high, except for certain fractional two's
complement applications (see multiplier input / output formats).
Flow through control. When high, both MSP and LSP registers are by-passed.
7217 X, Y, RND, LSP and MSP register clock input.
7216 X register clock input. Also clocks RND register.
7216 Y register clock input. Also clocks RND register.
7216 LSP register clock input.
7216 MSP register clock input.
7217 X register clock enable. Also enables RND register clock.
7217 Y register clock enable. Also enables RND register clock.
