Beschreibung

This reference design demonstrates an efficient, low noise 5-rail power-supply design for very high-speed DAQ systems capable of > 12.8 GSPS. The power supply DC/DC converters are frequency synchronized and phase-shifted in order to minimize input current ripple and control frequency content. Furthermore, any potential radiated electromagnetic interference (EMI) is minimized by using high performance HotRodTM packaging technology.

Eigenschaften

• Sampling rate up to 12.8GSPS, using timeinterleaved 12-bit RF-sampling ADCs
• Analog front end support up to 6-GHz bandwidth
• Fine sample clock phase adjustment (19 fs resolution)
• Phase synchronization of multiple ADCs
• Companion power reference design with a >85% efficiency at 12-V input
• JESD204B supporting 8, 16, or 32 JESD lanes, data rates up to 12.8 Gbps per lane

Typische Anwendungen

• Supply Rails for Op Amps, DACs, ADCs, and is provided in sensitive instrumentation, test and Other High-Precision Analog Circuitry
• Test and Measurement / Industrial Instrumentation
• Post DC-DC Converter Regulation and performance rails are required, consider TI’s Ripple Filtering
• Audio
• Rx, Tx, and PA Circuitry / Base Stations and Telecom Infrastructure
