TELEDYNE e2VEverywhereyoulook™ EV12AD550B Dual 12bits 1.6GSps ADC Space Grade PRELIMINARY DATASHEET OVERVIEW EV12AD550 is a dual S-band capable 12bit ADC intended for space applications that is built using a true single core architecture per channel providing high spectral purity. With a 3dB input bandwidth up to 4.3GHz, it allows for direct digitization in S-band without frequency down-conversion. Synthetic Aperture Radar systems will also be able to operate this ADC with reduced dynamic range at frequencies beyond 5GHz without frequency down-conversion. This device includes a multiple ADC chained synchronization feature. This would help designing large array of synchronous ADC for example in active antenna array or MIMO systems. Multichannel applications will benefit from a cross-talk isolation between inputs in excess of 80dB and Noise Power Ratio performance of 50dB in the first Nyquist zone and better than 45dB in the 4th Nyquist zone. This device comes in a hermetic flip chip CCGA323 package in Aluminum Nitride with improved thermal performance and is planned for QML-V and ESCC certification.

Dual channel 12 bits 1.6GSps ADC Description Description The EV12AD550 is a dual 12 bit 1.6GSps ADC featuring low latency LVDS parallel output with a built-in selectable 1:2 or 1:1 DEMUX to compromise between power consumption and ease of interfacing. The two channels can operate in phase or in opposition, thus allowing synchronous or interleaved sampling. Each channel is composed of a true single core ADC sampling at up to 1.6GSps. Based on an innovative architecture without internal interleaving, it provides high spectral purity. It offers an analog input bandwidth of up to 4.3GHz with 2 selectable...

Dual channel 12 bits 1.6GSps ADC 3 Specifications 3.1 Absolute maximum ratings Absolute maximum ratings are limiting and stressing values (referenced to GND = 0V), to be applied individually, while other parameters are within specified operating conditions. Exposure above those conditions may cause permament damage. Long exposure to maximum ratings may affect device reliability. Functional operation at any other conditions those indicated in the operational section may affect devices performances and reliability.
