The SynthePHY is a highly integrated device designed for use in wireless Remote Radio Head (RRH) applications. It provides two independent high-speed, bi-directional, serial to 10-bit parallel interfaces, jitter attenuation of the recovered clock, and a programmable system clock synthesizer unit. The programmable clock synthesizer is synchronized to the recovered clock and provides a variety of low-phase-noise clock sources for RRH system components such as data converters, RF oscillators, and signalprocessing devices. The two serializer-deserializer (SERDES) channels are CPRI, OBSAI RP3, and IR compliant. Integrated hardware support for link delay calculation is also provided.
- Enables implementation of CPRI compliant, OBSAI RP3 compliant, and IR compliant interfaces
- Generates low-jitter, low-phase-noise clock outputs for driving high performance data converters, RF synthesizers, and DSP subsystems
- Supports a Serial Peripheral Interface (SPI) control plane interface for device configuration
Example Application: Multi-Standard Remote Radio Module
