GS12281

12G UHD-SDI Re-timing Cable Driver

Key Features

Applications

•

Dual non-inverted 75Ω cable interface with on-chip

termination

Next Generation 12G UHD-SDI infrastructures designed to

support UHDTV1, UHDTV2, 4K D-Cinema and 3D HFR and HDR

production image formats. Typical applications: Cameras,

Switchers, Distribution Amplifiers and Routers.

•

SMPTE ST 2082-1, ST 2081-1, ST 424, ST 292-1 and ST 259

compliant input/output

•

Multi-standard operation from 1Mb/s to 11.88Gb/s

In addition to standard SMPTE rates, the device also supports

re-timing of DVB-ASI at 270Mb/s, and MADI at 125Mb/s.

Description

The GS12281 is a low-power, multi-rate, re-timing cable driver

supporting rates up to 12G UHD-SDI. It is designed to receive

100Ω differential input signals, automatically recover the

embedded clock from the digital video signal and re-time the

incoming data, and transmit the re-timed signal over 75Ω coaxial

cables. The 100Ω trace input supports up to 17dB of insertion loss.

•

3D Input Signal Eye Monitor

PRBS generator and checker

Cable driver mode features:



Wide swing control



Pre-emphasis to compensate for significant insertion loss

between device output and BNC

The integrated eye monitor provides non-disruptive mission

mode analysis of the post equalized input signal. The 256x128

resolution scan matrix allows accurate signal analysis to speed up

prototyping and enable field analysis.



Automatic/manual output slew rate control

Manual or automatic re-timer bypass

Manual or automatic Mute or disable on LOS

Built in macros enable customizable cross section analysis and

quick horizontal and vertical eye opening measurements.

•

Trace equalizer features:



Integrated 100Ω, differential input termination

Automatic power down on loss of signal

Adjustable carrier detect threshold

DC-coupling from 1.2V to 2.5V CML logic

Trace equalization to compensate for up to 20” FR4 at

11.88Gb/s

With high phase consistency between scans and configurable

space and time thresholds, algorithms can be deployed in the

field to analyze long term signal quality variation (Bathtub Plot) to

reduce costly system installation debug time for intermittent

errors. The two cable drivers have highly configurable

pre-emphasis and swing controls to compensate for long trace

and connector losses. Additionally, automatic and user selectable

output slew rate control is provided for each cable driver output.



Automatic input offset compensation

•

CDR features:

The GS12281 is pin compatible with the GS12181 single input,

and the GS12182 dual input 12G UHD-SDI Multi-rate Re-timing

Cable Drivers, the GS12081 12G UHD-SDI Multi-rate Cable Driver,

as well as the GS3281 3G SDI Multi-rate Re-timing Cable Driver.



Manual or automatic rate modes

Wide Loop bandwidth control

Re-timing at the following data rates: 125Mb/s, 270Mb/s,

1.485Gb/s, 2.97Gb/s, 5.94Gb/s, and 11.88Gb/s. This

includes the f/1.001 rates.



Note: For the GS12281 to be pin compatible with the GS12182,

careful design considerations are required. Contact for your local

Semtech FAE for details.

Additional Features

•

Single 1.8V power supply for analog and digital core

2.5V or 3.3V for cable driver output supply

GSPI serial control and monitoring interface

Four configurable GPIO pins for control or status monitoring

Wide operating temperature range: -40ºC to +85ºC

Small 6mm x 4mm 40-pin QFN

Pin compatible with the GS12181, GS12182, GS12081, and

GS3281

•

Pb-free/Halogen-free/RoHS and WEEE compliant package
