Renesas Electronics Corporation Integrated Circuits (ICs) - Clock-Timing - Clock Generators, PLLs, Frequency Synthesizers 8A34011E-000AJG8

The 8A34011E-000AJG8 is a port synchronizer designed for frequency and time/phase synchronization in packet-based and physical layer-based equipment. It features eight independent timing channels that can function as frequency synthesizers, jitter attenuators, Digitally Controlled Oscillators (DCO), or Digital Phase Lock Loops (DPLL). The device supports a wide range of applications, including core and access IP switches, synchronous Ethernet equipment, and telecom boundary clocks. This product can generate output frequencies from 0.5Hz to 1GHz with a jitter performance of less than 150fs RMS over a frequency range of 10kHz to 20MHz. It offers 12 differential and 24 LVCMOS outputs, with selectable output voltages and swing levels. The device also supports multiple input configurations, allowing for up to eight differential and 16 single-ended clock inputs, which can operate at frequencies from 1kHz to 1GHz. The 8A34011E-000AJG8 includes advanced features such as programmable DPLL Digital Loop Filters, automatic reference selection, and the ability to phase align clock outputs with sync inputs. It is equipped with I²C and SPI interfaces for configuration and control, and it can store multiple configurations in its internal memory. This makes it suitable for high-performance applications requiring precise timing and synchronization.
