Partner Product

Model 6232  (Pentek Inc)
Model 6232 is a general-purpose 32-channel narrowband digital receiver VIM-4 module. It attaches to VIM-compatible processor boards and connects directly to all four processors.

Product Highlights

*Four 16-bit digital inputs on two FPDP connectors *Dual Field Programmable Gate Arrays (FPGAs) *Front panel FPGA I/O *All downconverters can select any of the four inputs *40 MHz input clock rate (ƒs) *2 kHz to 1 MHz output bandwidths for ƒs = 40 MHz *Front panel clock/sync bus for board synchronization

Product Description

Front End

The Model 6232 accepts four 16-bit

digital inputs on two front panel FPDP

connectors supporting data rates up to

40 MHz. Data from each 16-bit input flows

into a FIFO to allow synchronization, and

is in turn transferred to the digital receiver

section. Data from any of the four inputs

can be directed to any of the 32 receiver

channels or directly to the FPGAs.

Each FPDP connector is clocked individually.

Clock information is sent to a controller

for data clocking and sync.

Digital Downconverters

The 6232 includes eight Graychip

GC4016 quad narrowband digital

downconverter chips. The maximum input

sampling rate for the GC4016 is 80 MHz.

Each device includes four independently

tuned channels capable of center frequency

tuning from DC to 20 MHz, and with output

bandwidths ranging from 2 kHz to 1

MHz (for 40 MHz sample clock).

Each GC4016 accepts up to three 16-bit or

four 14-bit parallel inputs from the input

FIFOs. Internal crossbar switches allow all 32

downconverter channels on the board to

select any of the four inputs for flexible



The front panel clock and sync bus allow

one 6232 to act as a master, driving the

sample clock out to a front panel cable bus

using LVDS differential signaling. Multiple

slaves can then be clocked synchronously

with the master. Additional sync lines on

the bus allow synchronization of the local

oscillator phase, frequency switching, decimating

filter phase, and FIFO data collection

on multiple 6232’s.
