DBBC Status Report

1) Summary of firmware development and results of tests and Haystack comparison

2) Status of FiLa10GE board (needed for Mark 5C and e-VLBI)

3) Status of DBBC company "HAT-Lab"

All the hardware completedFirmware Team (IRA, MPI, Arcetri)New firmware for Core2 in down conversion

configuration:- xx.99 problem solved- fringe amplitude with still

dependence on the IF amplitude levels: improvement

under development by a dedicated working

teamNew firmware for Core2 in fixed tuned wide

band:- Fully developed - Successful compatibility test with Haystack

FILA10G Ethernet Interface

Hardware complete (2 XFP + 2 SFP)Firmware Working Team (IRA, MPI,

Metsahovi, SHAO)Firmaware on prototype now running in one

board2 x 4.096 Gbps bidirectional (with std VLBI clock)2 x 8.192 Gbps bidirectional (with std VLBI clock)protocol UDP/IP with VDIF

Output on 2 optical fibers and 2 copper (1 Gbps ea.)

Developed additional interface Optical-CX4 (copper ) for MK5C

HAT-LABSpin-off company approved by INAF on April

BonnAdditional bureaucracy still running, the

spin-off not still operational until completion of all the procedures

Orders already pending for AuScopeProduction capability is about 4 systems / 4

monthsEVN production scheduling required

General DBBC very flexible in number of IF input and output

Input and output can be copper and/or optical fibers
