EV12AQ600 Quad 12bit 1.5 Gsps ADC with embedded cross-point switch, Digitizing up to 6 GSps Datasheet 1203 OVERVIEW EV12AQ600 is a quad channel 12-bit 1.5 GSps ADC. The built-in Cross-Point-Switch (CPS) allows multimode operation with the capability to interleave the four independent cores in order to reach higher sampling rates. In 4-channel operating mode, the four cores can sample, in phase, four independent inputs at 1.5 GSps. In 2-channel operating mode, the cores are interleaved by 2 in order to reach 3 GSps sampling rate on each of two inputs. In 1-channel operating mode, a single input is propagated to each of the four cores which are interleaved by 4 in order to reach a sampling rate of 6 GSps. This high flexibility enables digitization of IF and RF signals with up to 3 GHz of instantaneous bandwidth. With an extended input bandwidth above 6 GHz (EFPBW) the EV12AQ600 allows sampling of signals directly in the C-band (4-8 GHz) without the need to translate the signal to baseband through a down-conversion stage. The ADC includes a multiple ADC chained synchronization feature to enable design of multichannel systems found in phased-array or MIMO applications. The EV12AQ600 enables the qualification of a single component which is capable of meeting a wide variety of application needs from single to multi-channel, from baseband to more than 6 GHz of input bandwidth. The latency is 126 system clock cycles. The device is built in a non-hermetic flip-chip package using HiTCE glass ceramic material in order to reach optimized RF performance and higher pin density. This circuit is designed, manufactured and will be qualified to be compliant with ESCC (European Space Components Coordination) and QML-Y space requirements.

Figure 1 - Quad 12-bit ADC with 12Gbps serial link EV12AQ600 is a quad 12 bit 1.5Gbps ADC featuring a built in cross-point switch (controlled thru the SPI) allowing 1, 2 or 4 channel digitizing at respectively 6 GSps, 3 GSps or 1.5 GSps data rate. The four ADC cores can operate in phase or interleaved (option controlled thru the SPI). External clock must be provided at four times the individual sampling rate. The architecture uses four high sampling rate single cores (up to 1.5GSps) without interleaving thus providing high level of spectral purity. Data is output on a short latency serial link...

2 SPECIFICATIONS 2.1 Absolute Maximum Ratings Absolute maximum ratings are limiting values (referenced to GND = 0V), to be applied individually, while other parameters are within specified operating conditions. Exposure above those conditions may cause permanent damage. Long exposure to maximum ratings may affect device reliability Table 1._Absolute Maximum ratings All integrated circuits have to be handled with appropriate care to avoid damages due to ESD. Damage caused by inappropriate handling or storage could range from performance degradation to complete failure. Input buffers and associated...
