Description
The GS6151 is a low-power, multi-rate serial digital CDR
designed to automatically recover the embedded clock
from a digital video signal and re-time the incoming video
data.
The GS6151 will recover the embedded clock signal and
re-time the data from 6G UHD-SDI signals compliant with
SMPTE ST 2081. In addition, it can also re-time SMPTE ST
259-C, SMPTE ST 292, SMPTE ST 424 or DVB-ASI compliant
digital video signals as well as MADI audio streams.
The GS6151 features two high-speed differential signal
inputs feeding a 2:1 input selector. Input termination is
on-chip for seamless matching to 100Ω differential
transmission lines. The input selector is a component of a
video switching system with tightly constrained timing
requirements.
The GS6151 includes programmable trace equalization to
compensate for high-frequency losses associated with
board-level interconnect.
Two CML outputs interface seamlessly to devices with a
CML input reference between 1.2V and 2.5V.
Programmable output swing and de-emphasis provide
flexibility in managing signal integrity of the output signals.
The GS6151 can operate in either automatic rate detection
or manual rate selection mode. In auto mode the device
will automatically detect and lock onto incoming data
signals at any supported rate.
