FX366 – 30 GHz TDR/Sample & Hold
The FX351C is a high-performance, differential, low-power dissipation, dual rank, Sample & Hold Amplifier (S&HA), targeted at wideband, modestly sub-sampled data-acquisition applications. The FX351C tracks analog DC to 45GHz signals and performs at least 8-bit (non-averaged, full-scale) sampling rates from 20M to 950MS/s. The FX351C is our highest bandwidth sample and hold that is available in our 2.9mm QFN package.
Product Description
Key Features
- Single clock/dual rank architecture
- 2.9mm ceramic/air-cavity QFN16 package
- Single -5V Vee supply
- 750mW power dissipation
- High-isolation
Applications
- Instrument: NRZ digital sub-sampling, to 56Gb
- 56G symbol-rate PAM4 eye, for communications
- RF Automated Test Equipment (ATE)
- Bandwidth & linearity extension of ADCs
- Software defined radio
Due to the compact size and low power, the FX351C can extend the bandwidth/linearity of systems that employ commercial ADCs.
