Texas Instruments announced that the ADS54J60 is the industry's first 16-bit 1-GSPS analog-to-digital converter (ADC) and the first device to achieve a signal-to-noise ratio (SNR) of more than 70dBFS at 1-GSPS. The company also announced the highest density quad 14-bit 500-MSPS ADC ADS54J54.
In order to optimize the signal chain, TI's new 4.5 GHz LMH6401 fully differential digital variable gain amplifier (DVGA) provides the widest bandwidth through DC coupling and allows the acquisition of low-frequency and high-frequency signals without being limited by the AC coupling system. Balanced-unbalanced converter. ADCs work with amplifiers to provide the highest performance, lowest power consumption, and space savings in defense and aerospace, test and measurement, and communications infrastructure applications.
The main features of the ADS54J60 and ADS54J54 are: 1-The highest speed in its class: 16-bit 1-GSPS ADS54J60 ADC and 14-bit 500-MSPS ADS54J54 can provide higher frequencies and perform more accurate signal analysis. 2 – Highest dynamic performance: Compared with competitive ADCs, the ADS54J60 has an SNR of more than 3dB (70 dBFS at FIN = 170 MHz), a low noise floor of -159 dBFS / Hz, and a spurious-free dynamic range of 86dBc ( SFDR). These features enable high spectral purity and detect weak signals in the presence of larger harmful blockers. 3-High Density: The ADS54J54 is 50% smaller than competing ADCs and offers four channels in a 9mm x 9mm package. The ADS54J60 offers two channels in a 10mm x 10mm package. 4-Reduce data interface speed and external processor resources: Integrated digital down converter (DDC) provides programmable extraction or bypass mode. 5-Simplified circuit board wiring and device synchronization: Both ADCs provide high-speed JESD204B serial data interfaces, which simplifies connection to the processor, including 66AK2L06 system-on-chip and FPGA. 6 – Low power: Both new ADCs consume 20% less power than competing ADCs.
A complete support kit is available for system designers, including samples, product evaluation modules (EVM) (ADS54J60EVM, ADS54J54EVM, LMH6401EVM), and data converter capture cards and pattern generators (TSW14J56EVM). The company said that the IBIS model can be used for ADCs and amplifiers, and the TINA-TI model can be used for amplifiers.
