TI AND XILINX PROVIDE EASIEST-TO-USE INTERFACE
SOLUTION BETWEEN
HIGH-SPEED DATA CONVERTERS AND FPGAS
Companies Release Deserializer Reference Design
for the TI ADS527x Data Converter Family and the Xilinx Virtex-II
and Spartan-3 FPGAs
DALLAS, TX. (Nov. 1, 2004) - Texas Instruments Incorporated
(TI) (NYSE: TXN) and Xilinx (NASDAQ: XLNX), the world's leading
supplier of programmable logic solutions, today announced immediate
availability of an FPGA-based deserializer reference design jointly
developed by TI and Xilinx. This new reference design, which deserializes
bit streams from TI's ADS527x analog-to-digital converter (ADC)
family, and accompanying application note provide a quick and easy
solution for designers to integrate a serial, high-speed LVDS receiver
into the Xilinx Virtex-II series, Virtex-II Pro and Spartan-3 FPGAs.
Systems designers can now effectively leverage the serial-to-parallel
processing capabilities and software programmability of FPGAs to
accelerate operations for specialized, high-performance processing
functions. The ability to achieve much higher levels of overall
system performance is especially important for multi-channel applications
such as ultrasound, instrumentation and wireless communications.
Designers can obtain more detailed information on how best to interface
Xilinx FPGAs to TI's high-speed data converters for their specific
applications by going to www.ti.com/ADS527x.
LVDS Reference Design files can also be downloaded directly from
Xilinx at: http://www.xilinx.com/bvdocs/appnotes/xapp774.pdf.
High Performance LVDS Interface
The deserializer reference design accepts up to eight channels simultaneously
and provides automatic de-skew and clock alignment functions. Each
ADC output is serialized and transmitted through a separate LVDS
serial pair. An independent frame clock and serial data clock are
provided to allow for easy de-serialization. The Xilinx reference
design provides the necessary timing to accept these extremely fast
input signals and translate them into commonly used parallel output
busses.
The serial LVDS interface format provides several distinct advantages
to the system manufacturer. Lower pin count, both on the ADC and
the FPGA, means less routing lines and lower cost boards. The LVDS
interface itself is a differential current mode interface that provides
both immunity to external noise and extremely low crosstalk injection
of noise into the printed circuit board. These advantages translate
to lower cost and higher system reliability.
About TI's ADS527x Data Converters
The ADS527x family of eight-channel ADCs includes 40, 50, 65 and
70 MSPS (mega samples per second) versions in 12-bit resolution,
and 40, 50 and 65 MSPS versions in 10-bit resolution. All products
in this family are pin compatible, providing a simple upgrade path
in both sample rate and resolution.
The ADS527x family features exceptional signal-to-noise ratio of
70.5dB (60.5dB for the 10-bit family) at 10MHZ input frequency and
only 123mW of power per channel at 65 MSPS (138mW/channel at 70
MSPS) - the lowest power of any competitive product. The devices
allow high system density for multi-channel applications. (See www.ti.com/sc04020
for product information).
About Xilinx FPGAs
Xilinx Virtex-II series Platform FPGAs deliver the highest performance
and highest density of any programmable logic solution available
today. With densities ranging from 40,000 to eight million-system
gates, Virtex-II and Virtex-II Pro Platform FPGAs have been broadly
adopted in sophisticated, high-performance applications historically
dominated by application-specific integrated circuits (ASICs).
Spartan-3 is the only low-cost FPGA that provides up to 344 differential
I/O pairs for LVDS interfacing. Combined with the break-through
price points offered by these devices, companies can now implement
one of the lowest cost LVDS deserializer designs with Spartan-3
FPGAs.
