National Semiconductor dual 16-bit 160 MSa/s pipeline ADC
National Semiconductor has introduced what is claimed to be the first dual-channel 16-bit, 160 MSa/s pipeline analog-to-digital converter (ADC).
With two high-speed channels, the device is targeted at multi-carrier, multi-standard GSM/EDGE, WCDMA, LTE and WiMAX wireless base stations.
The converter consumes less than half the power per ADC channel (650 mW) compared with single-channel 16-bit 160 MSa/s pipeline ADCs and offers large input-bandwidth (1.4 GHz) and claimed best dynamic performance at high input frequencies.
It delivers 91.2 dB full scale spurious-free dynamic range, 76.3 dB signal-to-noise ratio and 97.3 dB higher-order harmonic distortion at 197 MHz input frequency.
The device operates on dual power supplies of 1.8 and 3.0 V, with power-down and fast recovery, and features dual low-voltage differential signalling outputs for interfacing to field-programmable gate arrays and application-specific integrated circuits.
An evaluation board interfaces directly with the WaveVision 5 software and data capture board to simplify and accelerate evaluation of the device, which can be teamed with the dual-channel LMH6517 digitally controlled variable gain amplifier (DVGA) or the LMH6554 fully differential amplifier. The LMX2541 frequency synthesiser or one of the LMK04000 series of clock jitter cleaners can be added.
The ADC16DV160 is supplied in a 68-pin LLP package.
