National Semiconductor has introduced a dual-channel
16-bit, 160 mega-samples per second (MSPS) pipeline analog-to-digital
converter (ADC), claimed to be the industry's first .
The ADC16DV160 is targeted at multi-carrier,
multi-standard GSM/EDGE, WCDMA, LTE and WiMAX wireless basestations.
According to National, the ADC16DV160 consumes less than half the power
per ADC channel (650
mW) compared to competing single-channel 16-bit 160-MSPS pipeline ADCs,
while offering the largest input-bandwidth (1.4 GHz) and the industry's
best dynamic performance at high input frequencies. The ADC16DV160
delivers 91.2 decibels full scale (dBFS) spurious-free dynamic range
(SFDR), 76.3 dBFS signal-to-noise ratio (SNR) and 97.3 dBFS
higher-order harmonic distortion at 197 MHz input frequency.
The ADC16DV160 operates on dual power supplies, 1.8V and 3.0V, with
power-down and fast recovery, and features industry-standard dual
low-voltage differential signaling (LVDS) outputs for interfacing to
field-programmable gate arrays (FPGAs) and application-specific
integrated circuits (ASICs).
Evaluation boards and
An evaluation board interfaces directly with National's WaveVision 5
software and data capture board to simplify and accelerate evaluation
of the ADC16DV160. The WaveVision 5 system is a data acquisition and
analysis tool designed to help users evaluate National's signal path
products. The ADC16DV160 can be teamed with the dual-channel LMH6517
digitally-controlled variable gain amplifier (DVGA) or the LMH6554
fully differential amplifier. By adding the LMX2541 frequency
synthesizer or one of National's LMK04000 family of clock jitter
cleaners, a system designer can form a complete signal path solution.
Pricing and availability
The ADC16DV160 is supplied in a 68-pin LLP package and is priced at
$140 each in 1,000-unit quantities. The ADC is sampling now with
production quantities scheduled for late fourth quarter 2009. For more
