HD-LINX ™ II GS9060
SD-SDI and DVB-ASI Deserializer
with Loop-Through Cable Driver
PRELIMINARY DATA SHEET
KEY FEATURES
DESCRIPTION
• SMPTE 259M-C compliant descrambling and NRZI →
NRZ decoding (with bypass)
The GS9060 is a reclocking deserializer with a serial loop-
through cable driver. When used in conjunction with any
Gennum cable equalizer and the GO1525 Voltage
Controlled Oscillator, a receive solution can be realized for
SD-SDI and DVB-ASI applications.
• DVB-ASI sync word detection and 8b/10b decoding
• serial loop-through cable driver output selectable as
reclocked or non-reclocked
• dual serial digital input buffers with 2 x 1 mux
• integrated serial digital signal termination
• integrated reclocker
In addition to reclocking and deserializing the input data
stream, the GS9060 performs NRZI-to-NRZ decoding,
descrambling as per SMPTE 259M-C, and word alignment
when operating in SMPTE mode. When operating in DVB-
ASI mode, the device will word align the data to K28.5 sync
characters and 8b/10b decode the received stream.
• descrambler bypass option
• adjustable loop bandwidth
• user selectable additional processing features
including:
Two serial digital input buffers are provided with a 2x1
multiplexer to allow the device to select from one of two
serial digital input signals.
- TRS, ANC data checksum and EDH CRC error
detection and correction
The integrated reclocker features a very wide Input Jitter
Tolerance of 0.3 UI (total 0.6 UI), a rapid asynchronous
lock time, and full compliance with DVB-ASI data streams.
- programmable ANC data detection
- illegal code remapping
• internal flywheel for noise immune H, V, F extraction
• FIFO load Pulse
An integrated cable driver is provided for serial input loop-
through applications and can be selected to output either
buffered or reclocked data. This cable driver also features
an output mute on loss of signal, high impedance mode,
and adjustable signal swing.
• 20-bit / 10-bit CMOS parallel output data bus
• 27MHz / 13.5MHz parallel digital output
• automatic standards detection and indication
• 1.8V core power supply and 3.3V charge pump power
supply
The GS9060 also includes a range of data processing
functions such as error detection and correction, automatic
standards detection, and EDH support. The device can
also detect and extract SMPTE 352M payload identifier
packets and independently identify the received video
standard. This information is read from internal registers via
the host interface port.
• 3.3V digital I/O supply
• JTAG test interface
• small footprint compatible with GS1560A, GS1561,
GS1532 and GS9062
APPLICATIONS
TRS errors, EDH CRC errors and ancillary data checksum
errors can all be detected. A single ‘DATA_ERROR’ pin is
provided which is a logical 'OR'ing of all detectable errors.
Individual error status is stored in internal ‘ERROR_STATUS’
registers.
•
SMPTE 259M-C Serial Digital Interfaces
•
DVB-ASI Serial Digital Interfaces
Finally, the device can correct detected errors and insert
new TRS ID words, ancillary data checksum words, and
EDH CRC words. Illegal code re-mapping is also available.
All processing functions may be individually enabled or
disabled via host interface control.
