Description

The VT505 is a custom form factor which enables 16 ADC channels to be synchronized to IEEE1588/SyncE and/or to an external clock source (i.e. 1PPS from GPS).  Ideal for sonar applications.

Each ADC is 32-bit differential Δ∑ with sampling rate from 8 to 768 KHz. The S/(N+D) is ~112dB. Internal filters with four types of LPF and digital HPF.

Each of the analog inputs are mounted on its own custom daughter module. The versatility of the design allows the front-end analog design to be changed for application specific designs such as changing of the amplifiers, attenuators, filter, etc.

The module has an AMD Zynq Ultrascale+ FPGA to capture the analog signals. The control and data transport are via Ethernet.

The VT505 in conjunction with the VT801 and the VT979 chassis allows a total of 64 channels of analog input in a 4U rack mount space. Deploying multiples of VT979 allows hundreds, if not thousands, of the ADC to be fully synchronized to the network clock and/or a common external clock (i.e. 1PPS from the GPS).
