High-speed ADCs

25 May 2011 Analogue, Mixed Signal, LSI

Intersil has expanded its family of high-speed analog-to-digital converters (ADCs) for communications and data acquisition applications by introducing the 16-bit ISLA216P series.

The ISLA216P provides multichannel support, so that multiple ADCs can be precisely time-aligned, simplifying the design of simultaneously sampled multichannel systems. For advanced applications that require multiple input channels, including radar array processing, broadband communications, data acquisition systems, software defined radios, and communications test equipment, the ISLA216P is a suitable choice.

At a sample rate of 250 Megasamples per second (MSps), the ISLA216P25 consumes just 786 mW from its 1,8 V supply and is capable of providing a signal-to-noise ratio (SNR) of 75,0 dBFS and spurious free dynamic range (SFDR) of 87 dBc at a 30MHz input frequency. It is fully specified for input frequencies above 600 MHz, allowing designers of under-sampled or high IF systems to confidently utilise its 700 MHz full-power bandwidth.

Configurability is aided by features such as a serial peripheral interface (SPI) port which allows access to the channel gain and offset adjustments, as well as several power-saving modes. The internal clock duty cycle stabiliser and programmable clock divider simplify the challenge of clock distribution, and the programmable, built-in test patterns improve reliability by enabling remote signal integrity self-test capability.
