SI52111-A3-GM2

The SI52111-A3-GM2 is a clock / timing module designed for application-specific, next-generation network architectures, supporting clock synchronization and precision timing applications. The module comprises a highly reliable and accurate, single-chip clock / timing device, the SI52111, combined with two integrated voltage-controlled oscillators (VCXOs) and a programmable output buffer. The module can generate synchronous, low-jitter output frequencies from a single, low-cost device, reducing the clock / timing subsystem cost and complexity.

The SI52111-A3-GM2 clock / timing module provides a low-power, wide-range clock distribution solution for next-generation network architectures, and supports clock synchronization and precision timing applications. The module offers the full suite of clock outputs, including a wide variety of reference clocks for systems supporting multiple speed grades, BI and GCI clocks, and PTP Grandmaster alarms. The highly integrated design has integrated VCXO and programmable output buffer, providing stable and accurate timing while saving space and cost.

The SI52111-A3-GM2 is based on IDT’s patent-pending reference clock technology, which enables the integration of independent frequency references and offers low jitter performance across full frequency range. This module has a programmable output buffer capable of buffering up to five independent clock signals. The buffer can be programmed to drive different clock frequencies, with each signal having independent timing skew values and output slew rate. The module also features on-board clock-skew compensation and jitter attenuation mechanisms, enabling the delivery of low-jitter clocks with minimal distortion. The wide operating temperature range ensures stable performance over a wide range of temperatures, allowing for high-reliability clock distribution.
