Texas Instruments TPS7A8400RGRR | Demoboard TIDA-01027
Low noise power-supply reference design maximizing performance in 12.8 GSPS data acquisition systems
Overview
| Topology | Other Topology |
| IC revision | E1 |
Description
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.
Features
- 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
Typical applications
- Instrumentation, Medical, and Audio
