GS3140 Overview
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...
GS3140 Key Features
- Multi-standard operation at rates between 1Mb/s and 2.97Gb/s
- SMPTE ST 424, SMPTE ST 292 and SMPTE ST 259 pliant
- AES10 (MADI) patible
- Industry leading cable reach, with automatic cable equalization for different lengths of cable
- 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 (see Table 4-2)
- Ultra-low power mode for shorter cable reach
GS3140 Applications
- Upstream launch swing pensation 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
