Description
The GS9060 is a reclocking deserializer with a serial
loop-through cable driver. When used in conjunction
with any Gennum cable equalizer and the
GO1555/GO1525* Voltage Controlled Oscillator, a
received solution can be realized for SD-SDI and
DVB-ASI applications.
In addition to reclocking an 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.
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.
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.
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, adjustable signal swing.
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 SMTPTE 352M
payload identifier packets and independently identify
the received video standard. This information is read
from internal registers via the host interface port.
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
‘ORing’ of all detectable errors. Individual error status is
stored in internal ‘ERROR_STATUS’ registers.
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 the host interface control.
The GS9060 is Pb-free, and the encapsulation
compound does not contain halogenated flame
retardant (RoHS compliant).
