Overview
Together with the EB-GS3471-00 Evaluation Board, this document serves as a guide for
evaluating the GS3471. The GS3471 is a Semtech 3Gb/s, HD, SD SDI Receiver. For more
information on the GS3471, please refer to the Product Data Sheet (PDS-060500). This
document is partitioned into the following sections:
•EB-GS3471-00 User Guide
•EB-GS3471-00 Schematics
•EB-GS3471-00 Board Layout
•EB-GS3471-00 Bill of Materials (BOM)
Figure A below shows a block diagram of the features and the functions of the
EB-GS3471-00.
The board includes power supplies, USB control interface, two 3G-SDI inputs, one
GS3140 equalizer, a 3G-SDI loop-through output, a GS2988 multi-rate cable driver, a
GS3471 Receiver, a parallel video output connector, an audio output with four RCA for
AES audio, a 27MHz crystal, DIP switches, and a few status indication LEDs.
The GS3471 will automatically detect the input signal (J6 and J7) as SD-SDI, HD-SDI, or
3G-SDI. The deserialized video is available on the parallel output connector (J1). The
extracted audio is available as serial audio or AES on audio headers (J4 and J12). A serial
digital loop-through output (J10) is also available.
The EB-GS3471-00 also provides a JTAG interface used for boundary scan and a USB
interface to control the GS3471 and the GS3140 through the GSPI ports on the devices.

Figure 1-1: GS3471 Evaluation Board (EB-GS3471-00)
1.1 Power (J5 or J13)
The EB-GS3471-00 board is powered by a +5V supply through a Micro-B USB connector
(J5) or through the auxiliary power connector (J13). Not all USB ports are capable of
supplying enough current to power the board. In this case, use the external +5V
auxiliary power connector (J13) with the included DC power terminal. Connect the
auxiliary power supply before connecting the USB.
LED D10 is used to indicate if there is voltage present on the +5V input.
LED D7 is used to indicate if the voltage connected to J13 has been reversed.

1.2 SDI Input (J6 and J7)
The EB-GS3471-00 includes two 3G-SDI inputs DC-coupled to the GS3471. The applied
video stream will first pass through Semtech's GS3140 Cable Equalizer (PDS-060939)
before entering the DDI input pin of the GS3471. The pin J6 provides a DC path to the
GS3471 through the GS3140, while the pin J7 provides a direct AC path to the GS3471.

1.4 3G-SDI Loop Through (J10)
The output connector J10 is used for the 3G-SDI loop though output. The output for the
EB-GS3471-00 evaluation board is capable of the following standards:
•SMPTE 424M
•SMPTE 292M
•SMPTE 259M
The EB-GS3471-00 evaluation board supports DVB-ASI at 270Mb/s and data rates from
270Mb/s to 2.97Gb/s. The output is configured for a single ended coaxial cable
terminated with a BNC connection.
1.5 Video Header (J1)
Parallel video data with the PCLK and timing signals H, V, and F are available on a 60-pin
connector (J1). Using AB-GS3471-00 will allow the EB-GS3471-00 to interface to legacy
evaluation boards.

1.9 Modes of Operation
The GS3471 supports four distinct modes of operation that can be accessed through the
GUI or through the GSPI interface to internal registers. These modes are: SMPTE mode,
Data-Through mode, DVB-ASI mode, and Standby mode.
The GS3471 can automatically detect the format of the incoming signal. If the format of
the incoming signal is not recognized, the GS3471 defaults into SMPTE Bypass mode.
Alternatively, the device may be forced into any of the four modes through the GUI.
In SMPTE mode, the GS3471 performs full SMPTE processing, and features a number of
signal integrity checks and measurement capabilities.
In DVB-ASI mode, 8b/10b decoding is applied to the received data stream.
In SMPTE Bypass mode, all forms of SMPTE and DVB-ASI decoding are disabled, and the
device can be used as a simple serial-to-parallel converter without incurring the latency
penalties associated with SMPTE or DVB-ASI mode.
The device can also operate in a several lower power modes:
•Sleep
•Standby
•Standby with PCLK
•Sleep with SDO
•Standby with SDO Retimed
•Standby with SDO with PCLK
•Standby with SDO Retimed with PCLK
D5 Green Yes GS3471 Y/1ANC, when Data Stream 1 ancillary data is
detected, LED is active.
D6 Green Yes GS3471 When DATA ERROR is detected, LED is active.
D7 Red No — Reverse polarity. When polarity is reversed on
J13, LED is active.
D10 Green No — When power is present on the 5V input J5 and
J13, LED is active.
D11 Green No — When internal +3.3V is good, LED is active.
D13 Green No — When internal +2.5V is good, LED is active.
D15 Green No — Reset indicator, When LED active
EB-GS3471-00 is not in reset.
D16 Green No — When internal +1.8V is good, LED is active.
D18 Green No — When internal +1.2V is good, LED is active.
