Pentek is targeting software radio designs with its Model 7152, quad 200MHz, 16-bit A/D digitiser with a 32-channel digital down converter (DDC) configured in a PMC format.

The module has a factory-installed IP core for users who want to purchase a product with the critical signal-processing functions already installed and operational. It is suitable for fulfilling the requirements of real-time software radio, beamforming, signal-intelligence and radar systems.

Proprietary signal-processing techniques are used to provide features such as 200MHz sampling-rate DDCs, channel summation and power meters with threshold detectors.

Another feature are the 32 power meters that continuously measure the individual average power output of each of the 32 DDC channels. The time constant of the averaging interval for each meter is programmable for up to 16k samples.

The 32 threshold detectors automatically send an interrupt to the processor if the average power level of any DDC falls below or exceeds a programmable threshold. The built-in power meters and threshold detectors offload these tasks from a downstream processor and present average power measurements for each channel in easy-to-read registers.

The 7152 PMC module is also available in a variety of additional form factors. The 7652 is a PCI board, while the 7252 and 7352 are 6U and 3U Compact PCI boards, respectively.
