Description
The GS1559 is a reclocking deserializer with a serial
loop-through cable driver. When used in conjunction
with the GS1574 Automatic Cable Equalizer and the
GO1525 Voltage Controlled Oscillator, a receive
solution can be realized for HD-SDI, SD-SDI and
DVB-ASI applications.
In addition to reclocking and deserializing the input data
stream, the GS1559 performs NRZI-to-NRZ decoding,
descrambling as per SMPTE 292M/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 鹵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, and
automatic dual slew-rate selection depending on
HD/SD operational requirements.
The GS1559 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.
Line-based CRC errors, line number errors, TRS errors,
EDH CRC errors and ancillary data checksum errors
can all be detected. A single 鈥楧ATA_ERROR鈥?pin is
provided which is a logical 'OR'ing of all detectable
errors. Individual error status is stored in internal
鈥楨RROR_STATUS鈥?registers.
Finally, the device can correct detected errors and
insert new TRS ID words, line-based CRC words,
ancillary data checksum words, EDH CRC words, and
line numbers. Illegal code re-mapping is also available.
All processing functions may be individually enabled or
disabled via host interface control.
