Product Overview

The SynthePHY 3G-Lite is a programmable System Clock Synthesizer and 2-Port SERDES designed for use in wireless Remote Radio Head (RRH) applications. It provides two independent high-speed, bi-directional, serial-to-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 it provides a variety of low phase noise clock sources for RRH system components such as data converters, RF oscillators and signal processing devices. The two serializer-deserializer (SERDES) channels support rates up to 3.072 Gbps and are CPRI, OBSAI RP3, and IR compliant. Integrated hardware support for data path delay calibration is also provided.

Benefits
  • Enables implementation of CPRI-compliant, OBSAI RP3- compliant, and IR-compliant interfaces.
  • Generates low jitter, low phase noise clock outputs for driving subsystems.
  • Supports a Serial Peripheral Interface (SPI) control plane interface for device configuration.

Example Application: Multi-Standard Remote Radio Module
