GS6150 GS6150 Multi-Rate 6G UHD-SDI Reclocker Gennum Products Key Features Applications SMPTE ST 2081, ST 424, ST 292, and SMPTE ST 2081, SMPTE ST 424, ST 259-C compliant SMPTE ST 292, SMPTE ST 259-C coaxial cable serial digital interfaces Supports retiming data at rates of 125Mb/s, 270Mb/s, 1.485 and 1.485/1.001Gb/s, 2.97 and 2.97/1.001Gb/s, EN50083-9 DVB-ASI interfaces 5.94 and 5.94/1.001Gb/s MADI standard Supports retiming of DVB-ASI signals Automatic or Manual Rate Selection Description Detected rate indication in Auto Mode The GS6150 is a low-power, multi-rate serial digital reclocker designed to automatically recover the embedded 4:1 input selector patented technology clock from a digital video signal and re-time the incoming Option of two reclocked data outputs video data. Four configurable GPIO pins with ability to output The GS6150 will recover the embedded clock signal and re- device status, including: time the data from 6G UHD-SDI signals compliant with Lock Detect SMPTE ST 2081. In addition, it can also re-time SMPTE ST Loss of Signal (LOS) 259-C, SMPTE ST 292, SMPTE ST 424 or DVB-ASI compliant Low/High bit-rate indication for slew-rate control of digital video signals as well as MADI audio streams. SDI cable drivers On-chip 100 differential input and output The GS6150 features four high-speed differential signal termination inputs feeding a 4:1 input selector. Input termination is on- Bypass support for rates up to 5940Mb/s chip for seamless matching to 100 differential transmission lines. The input selector is a component of a Manual Bypass function video switching system with tightly constrained timing Configurable automatic Bypass when not locked requirements. Option to use external reference or operate The GS6150 includes programmable trace equalization to referenceless compensate for high-frequency losses associated with Cascading reference buffer supports multiple board-level interconnect. reclockers using a single reference source Two CML outputs interface seamlessly to devices with a Input signal equalization and output signal CML input reference between 1.2V and 2.5V. de-emphasis to compensate for trace dielectric losses Programmable output swing and de-emphasis provide Single power supply operation at 1.8V flexibility in managing signal integrity of the output signals. 130mW typical power consumption (150mW with The GS6150 can operate in either automatic rate detection second output enabled) or manual rate selection mode. In auto mode the device Pb-free and RoHS compliant will automatically detect and lock onto incoming data Operating temperature range: -40C to 85C signals at any supported rate.

For applications which require rapid facilitates configuration and status monitoring of the signal lock, an external 27MHz reference may be used to set device. Multiple GS6150 devices can be daisy-chained the VCO frequency when not locked to the input signal. The together with a single 4-pin connection to the host system. presence of an external reference crystal is automatically This device is Pb-free, and the encapsulation compound detected by the device. does not contain halogenated flame retardant. This In systems that require passing of non-supported data component and all homogenous sub-components are rates, the GS6150 can be configured to either automatically RoHS compliant. or manually enter a bypass mode in order to pass the signal without reclocking.
