| National's ultra high speed analog-to-digital converter (ADC) family delivers unparalleled performance in a small package at the industry's lowest power, enabling energy-efficient and area-efficient solutions. The ultra high-speed ADC family maintains excellent dynamic performance at gigasample-per-second (GSPS) sampling rates and over large input bandwidths to support and enable many applications including direct RF sampling and SDR architectures in wideband communications, data acquisition, optical infrastructure, set-top boxes, microwave backhaul, gaming systems, and more. |
Breakthrough RF-Sampling ADCs Revolutionize Radio Architectures
National's 12-bit direct RF-sampling ADCs can directly sample input frequencies up to and beyond 2.7 GHz at up to 3.6 GSPS. A single direct RF-sampling ADC can replace an entire IF-sampling or ZIF-sampling radio signal path subsystem of mixers, LO synthesizers, amplifiers, filters, and ADCs, drastically reducing bill of materials (BOM) cost, design time, and board size, weight, and power. A wide array of applications such as 3G/4G wireless basestations, microwave backhaul, military, and wideband software-defined radio (SDR) can now achieve the benefits that RF-sampling provides.
The ADC12Dxx00RF family of ADCs improves upon National's existing 12-bit GSPS ADC products by expanding the frequency range over which National's superior dynamic range can be realized. The ADC12Dxx00RF delivers its excellent noise and linearity performance at RF frequencies beyond the 7th Nyquist zone. These five new ADCs are available in speed grades ranging from dual-channel 500 MSPS to single-channel 3.6 GSPS. They are pin-compatible with National's ADC12D1x00 and ADC10D1x00 families, enabling system designers to reuse a single design for multiple speed and resolution combinations. |
