Texas Instruments Wednesday announced it is applying its newest CMOS process technology to one of its biggest-selling digital signal processors -- the 320C549 -- and as a result, the 16-bit DSP will operate at 120 MHz instead of 100 MHz.
TI is also using the 0.18-micron drawn-gate process to launch anew, more powerful version of the xC54 DSP, doubling the on-chip
memory and offering 1.6 times the performance at 160 MHz. The
new C5416 has 128-k words of on-chip SRAM and higher speed
for greater flexibility inside a number of midrange telecom systems,
said Mark Mattson, product marketing manager for the C5000
series at TI in Houston.
The C5416 as well as souped up versions of existing C5410 and
C549 are the first standard DSP products to use TI's 0.18-micron
drawn (0.15-micron L-effective) process technology. Earlier this
month, the Dallas-based company announced it was using the
0.18-micron technology to produce custom DSPs as digital
baseband processors for cellular phones.
Now, TI is putting the new process to work in "catalog" DSP
products as it races competitors to offer faster processors with
lower power consumption. The new process technology will
increase the performance of existing products by 60 percent and cut
power consumption by 50 percent, said Mattson. TI began
shipping the C549 last summer and it has already delivered more
than 1 million of those processors, Mattson said.
Since then, TI has expanded its midrange offering in the C5000
series of DSP. The new 160-MHz 5416 is targeted at integrated
PBX functions and giving system makers the ability to add features,
like error correction, noise suppression, encryption, and speed
recognition. "This midrange segment is driven by the need for
greater flexibility in adding functions and features to product
families," Mattson said.
In addition to higher speeds, the new C5416 has a host port
interface that expands its ability to connect to either 8- or 16-bit
central processors. Samples of the C5616 will be available in the
fourth quarter of 1999 with volume shipments set for the second half
of 2000. It will cost $33.50 each in quantities of 10,000.
Samples of the 120-MHz speed-upgrade of the C549 are available
now with volume production set for the third quarter. Samples of the
120-MHz C5410 will be available in the third quarter with
production quantities becoming available in the fourth quarter this
