Digitising Receiver
DR068
Digitising Receiver
The DR068 latest Digitising Receiver builds on the strong
tradition of TDL Digital Frequency Discriminators (DFD’s).
The DR068 takes key performance elements from a number of
existing production DFD’s, integrating them for the first time into
a complete digital solution suitable for military environments.
The DR068 offers the benefits of TDL’s field-proven proprietary
SSS discriminator tiers coupled with the latest digital technology
to produce a receiver that not only measures frequency but is
capable of Digital Signal Processing (DSP) of the raw frequency
data.
DSP capability, is incorporated as standard; however, due to the
use of state-of-the-art FPGA technology, TDL is able to adapt
and add to the DSP capability to offer a DFD that is suitable for

DR068 also measures pulse parameters such as time of arrival
(TOA), pulse width (PW) and pulse amplitude.
POP and FMOP options available on request.
Data is output as a 96 bit Pulse Descriptor Word (PDW) as three
32 bit words via the industry standard Front Panel Data Port
(FPDP) connector. An optional 51 Way MDM interface is
available.
The DFD is packaged in an industry standard dual slot (8HP)
width plug-in format with DIN41612 interface for VME bus
applications, suitable for most modern day EW suite equipment
racks.

Operational range: of 0.6 to 1.4 bar.
Storage range: 0.3 to 1.4 bar.
VIBRATION
The unit is designed to meet the following vibration profile carried out on the worst axis: i.e. the force is

ELECTROMAGNETIC COMPATIBILITY
The unit is designed with regard to the requirements of MIL STD 461E. Compliance can only be satisfied by careful
design of the overall system particularly with regard to the interconnects between the DIFM and other parts of the
system. While the design will be executed with regard to the requirements of the relevant standards, TDL cannot
guarantee compliance if used inappropriately.

CONNECTOR INFORMATION
RF Input is via Front Panel sma(f) connector
Data Output via FPDP as detailed in Electrical Interface and Timing Information
DC Power via VME Backplane
ELECTRICAL INTERFACE AND TIMING
The primary interface for pulse measurement information is the Front Panel Data Port. This port is designed in
accordance with VITA 17-199x Rev 1.7 (24 Nov 1998).
The general operation is as described below:
• The DR068 transmits a Pulse Descriptor Word on the FPDP every time an RF pulse is detected and measured.
• The FPDP communication is one-way, however, the receiver is able to suspend transmission of PDW’s by
asserting
• the SUSPEND signal.
• The FPDP data word is 32-bit wide ‘frame’, a DR068 PDW is 96-bits long, therefore 3 32-bit frames are
• transmitted for every PDW
• The FDPD clock rate is 40MHz.
• A PDW transfer takes 5 clock cycles, therefore at 40MHz, it takes 125ns to TX a PDW.
NOTE: The DR068 has been designed and tested using a PC driven FPDP card, this card is manufactured by
VMETRO
(model number DPI02-FBU)

Front Panel Data transfer:
Each PDW will be transferred in five front panel data port clock cycles. The DR068 is the master
(transmitter) the host system is the slave (receiver).
The diagram below shows a full transfer plus start of next transfer.
NOTE: Refer to Front Panel Data Port Specifications, VITA 17-199x, for details of operation of the transfer
bus.
NOTES
1. The pulse width measurement will be derived from the output signal of the pulse detection circuit, i.e. it
will not be the width of pulse at 3 dB points.
2. Pulse widths longer than the maximum specified will be flagged as CW. A PDW will be generated at the
end of every 327.675us (with the CW flag set) until the pulse has been determined to have gone away.
3. The TOA counter will roll-over to zero every 21.47s.
