Equalizer
6G SDI equalizer
The GS6140 is a high-speed BiCMOS device designed to equalize and restore signals received over cable.
Features
- Multi-standard operation at rates between 1Mb/s and 5.94Gb/s
- SMPTE ST 2081 (proposed), SMPTE ST 292 and SMPTE ST 259 compliant
- AES10 (MADI) compatible
- Industry leading cable reach, with automatic cable equalization for different lengths of cable
- Performance optimized for 125Mb/s, 270Mb/s, 1.485Gb/s, 2.97Gb/s and 5.94Gb/s. Typical equalized length of Belden 1694A cable up to:
- 100m at 5.94Gb/s
- 200m at 2.97Gb/s
- 300m at 1.485Gb/s
- 550m at 270Mb/s
- 1.8V core power supply
- 83mW when DC-coupled at +1.2V
- Ultra-low power mode for shorter cable reach applications
- Upstream launch swing compensation from 250mVppd to 1000mVppd in 50mV steps (Default 800mVppd)
- Auto/Manual bypass (useful for low data rates with slow rise/fall times)
- Robust, noise-immune signal detection with squelch threshold adjustment
- Auto/Manual control of SLEEP/MUTE/DISABLE OUTPUT modes
- Data Rate detection and indication
- <MADI, MADI, SD, HD, 3G, 6G differentiation
- Digital cable length indication (CLI)
- Differential output supports DC-coupling from
- 1.0V to 2.5V CML logic and AC-coupling for other logic families
- Programmable/Rate-dependent output de-emphasis level and delay
- Host interface for status and control
- 6kV HBM ESD protection on all pins
- Wide operating temperature range of -40ºC to +85ºC
- Small footprint QFN–COL package (16-pin, 4mm x 4mm)
- Pb-free and RoHS compliant
Applications
- SMPTE ST 2081 (proposed), SMPTE ST 424, SMPTE ST 292, SMPTE ST 259 and AES10 coaxial cable serial digital interfaces
