The EV12AS350A from Teledyne e2v is a 12-bit Analog-to-Digital Converter (ADC) featuring four identical cores where all four ADCs are interleaved together delivering a 5.4 GSPS conversion rate. All four ADCs are clocked by the same external input clock signal delayed with the appropriate phase. It receives an external 5.4 GHz clock (maximum frequency) and preferably a low jitter sinewave signal.
In this ADC, the external clock signal is then divided by FOUR to generate the internal sampling clocks: The in-phase 1.35 GHz clock is sent to ADC A while the inverted 1.35 GHz clock is sent to ADC B, the in-phase 1.35 GHz clock is delayed by 90° to generate the clock for ADC C and the inverted 1.35 GHz clock is delayed by 90° to generate the clock for ADC D, resulting in an interleaved mode with an equivalent sampling frequency of 5.4 Gsps.
The ADC operates on a single supply of 4.8V, 3.3V and 1.8V and is available in an EBGA380 Package that measures 31 x 31 mm (1.27 mm pitch). It is ideal for high-speed data acquisition, direct RF down-conversion, ultra-wideband satellite digital receiver, 16 Gbps pt-pt microwave receivers, high energy physics, automatic test equipment, high-speed test instrumentation, LiDAR (Light Detection And Ranging), and software design radio applications.
