Semtech GS3140

Low-power, Multi-Rate Adaptive 3G SDI Equalizer

Add to Watch List

The GS3140 is a high-speed BiCMOS device designed to equalize and restore signals received over cable.

The device is designed to support SMPTE ST 424, SMPTE ST 292, SMPTE ST 259 and AES10 (MADI), and it is optimized for performance at 125Mb/s, 270Mb/s, 1.485Gb/s, and 2.97Gb/s.

The device supports MADI serial signals at 125Mb/s with peak-to-peak launch amplitude between 300mVppd and 600mVppd (with AES10 spec rise and fall times) and 800mVppd±10% (with SD-SDI rise and fall times).

Features


  • Multi-standard operation at rates between 1Mb/s and 2.97Gb/s
  • SMPTE ST 424, 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, and 2.97Gb/s. Typical equalized length of Belden 1694A cable up to:
    • 200m at 2.97Gb/s
    • 280m at 1.485Gb/s
    • 500m at 270Mb/s
  • 1.8V core power supply
  • Typical power consumption of 84mW when DC-coupled at 1.2V with OUTPUT_SWING = 0011b
  • Ultra-low power mode for shorter cable reach applications
  • Upstream launch swing compensation from 250mVppd to 1Vppd in approximately 50mVppd steps (Default 750mVppd)
  • 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 differentiation
  • Digital cable length indication (CLI)
  • Differential output supports DC-coupling from 1.2V 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
  • 3kV 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
  • Pin-compatible with the GS6140

Applications


  • SMPTE ST 424, SMPTE ST 292, SMPTE ST 259 and AES10 coaxial cable serial digital interfaces
