Description
The GS6150 is a low-power, multi-rate serial digital
reclocker designed to automatically recover the embedded
clock from a digital video signal and re-time the incoming
video data.
The GS6150 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 GS6150 features four high-speed differential signal
inputs feeding a 4:1 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 GS6150 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 GS6150 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.
