DS64EV400 Equalizer from National's PowerWise Energy-Efficient Product
Family Compensates Media Losses for up to 10 Gbps Data Transfers While
Consuming Only 94 mW per Channel
SANTA CLARA, Calif., Oct. 22 /PRNewswire-FirstCall/ -- A new
programmable quad equalizer from National Semiconductor Corporation (NYSE:
NSM) extends the reach of high-speed serial buses up to 10 Gbps data
transmission rates, while consuming only 94 mW per channel. The DS64EV400,
from National's PowerWise(R) energy-efficient product family, provides
high-speed signal transmission over backplanes and cables used in storage
area networking (SAN), communications infrastructure and automated test
equipment (ATE).
The DS64EV400 compensates for transmission medium losses and reduces
deterministic jitter for four data transmission channels. The device
provides 20 dB of boost to equalize up to 10m of CAT5 cable, up to 40
inches of FR-4 printed circuit board (PCB) at data transmission rates up to
6.4 Gbps and up to 30 inches of FR-4 at data rates up to 10 Gbps -- with
only 0.175 units interval (UI) of residual jitter at the equalizer output.
National fabricates this signal-conditioning part on its proprietary
silicon-germanium (SiGe) BiCMOS-8 process technology, which provides high
performance-to-power ratios for high-speed interface devices. Along with
featuring the lowest power at this performance level, inactive channels can
be automatically shutdown for further power savings of 85 percent per
channel.
The quad equalizer's features make it easy to use with
field-programmable gate arrays (FPGAs) and transmission media. Each
equalizer channel has eight equalization levels simultaneously set by three
control pins, or individually programmed through a serial System Management
(SM) Bus. The DS64EV400 supports both AC and DC-coupled data paths for
long-run-length PRBS-31 data patterns and balanced 8b/10b codes. It uses
differential current-mode logic (CML) inputs and outputs, and features 8 kV
of electrostatic discharge (ESD) protection. Additionally, the equalizer
includes a loss-of-signal (LOS) detect for each channel, operates over the
full -40 degrees C to 85 degrees C temperature range and is powered from
either a 2.5V or 3.3V supply.
National also is introducing the DS32EV400, a programmable quad
equalizer optimized for applications up to 3.2 Gbps that includes many of
the same features as the DS64EV400. These devices are the latest additions
to National's growing family of signal-conditioning equalizers, which
include the DS38EP100 and DS80EP100 power-saver equalizers, DS16EV5110
video cable equalizer, DS25BR110 LVDS equalizer, DS40MB200 dual mux-buffer,
and DS15BA101 and DS15EA101 cable extender chipset.
