PVG610 Baseband SoC Family
Provigent’s PVG610 family is an advanced Baseband System-on-a-Chip (SoC) solution for point-to-point wireless transmission systems. PVG610 SoCs support the complete processing chain - from user data interfaces of mixed signals through a high performance modem to carrier IF frequency. Multiple user data streams and types are encoded, modulated and converted to an analog signal for transmission. The received analog signal is digitized, demodulated, decoded and mapped to users' data streams. Innovative DSP mitigates analog impairments and allows overall system cost reduction.
The PVG610 family of SoCs offers a wide range of product types to optimize system cost for any type of application.
It includes the following main features:
General
Bit rate up to 400 Mbps
Adaptive Code and Modulation (ACM)
Redundancy through protection bus
Immunity to phase noise and phase hits
Modulation
QPSK; 16, 32, 64, 128, 256 QAM
