Installation

This section describes the unpacking, inspection, installation, and operation of the Symmetricom 5401 and 5402 Disciplined Rubidium Oscillators.

Unpacking and Inspection

The DRO is packaged in one shipping container. Inspect the unit for visible damage (scratches, dents, etc.). If the instrument is damaged, immediately notify both Symmetricom and the responsible carrier. Keep the shipping container and packing material for the carrier's inspection.

Note: When communicating with either Symmetricom or the responsible carrier regarding shipping damage, refer to the serial number. This number is located on the front panel of the 5401 and the rear panel of the 5402.

Symmetricom 5401 Installation Procedure

1.Install the unit in the desired location and connect the unit to its power source. Refer to Chapter 4 for specifications and connector pin assignments.

2.Connect the 1 PPS input to its 1 PPS source and connect the 1 PPS and 10 MHz outputs to their desired destinations.

Connection to the RS-232 I/O is not necessary for operation, but it is desirable in order to monitor status or enter new control parameters.

Symmetricom 5401 Initial Operation

Upon completion of the installation:

1.Apply power to the unit and observe that the green POWER LED indicator illuminates. Note that this unit does NOT contain a power switch.

2.After approximately five minutes, the yellow LOCK LED indicator will illuminate indicating that the internal Rubidium oscillator has attained lock (resonance). The 10 MHz outputs are now stable for use. Disciplining of the Rubidium oscillator will begin once a 1 PPS input is present.

5401, 5402 specifications

The Symmetricom 5402 and 5401 are highly regarded timing and synchronization solutions designed for telecommunications and data networking applications. These devices are part of the renowned line of precision timekeeping products developed by Symmetricom, which is now known as Microchip Technology.

The Symmetricom 5402 offers advanced capabilities, including GPS and precision time protocol (PTP) synchronization. It provides an accurate and stable time reference, crucial for industries that require precise timing to ensure system integrity and communication efficiency. The 5402 supports various synchronization protocols including IEEE 1588v2, ensuring interoperability with existing systems. This allows organizations to implement cutting-edge technologies while maintaining compatibility with older infrastructure.

On the other hand, the Symmetricom 5401 serves as a more compact and economical option tailored for specific applications where full GPS capabilities may not be necessary. This unit simplifies the synchronization process while still offering reliable performance. The 5401 provides multiple outputs including T1/E1 and 10 MHz, making it versatile for different network configurations.

Both models incorporate advanced oscillator technology that ensures accuracy and stability. They have a temperature-compensated crystal oscillator (TCXO) or optional oven-controlled crystal oscillator (OCXO) that provides superior frequency stability across a wide range of operating conditions. These devices also feature high-performance phase-locked loops (PLLs), which enhance their ability to maintain synchronization over time and under varying operational environments.

Additional features include robust network management capabilities, allowing for real-time monitoring and diagnostics through a user-friendly interface. The devices are equipped with multiple input/output ports that facilitate seamless integration into existing network architectures. The Symmetricom 5402 and 5401 support both local and remote management, enabling network administrators to maintain optimal synchronization performance.

In summary, the Symmetricom 5402 and 5401 deliver reliable, high-precision timing solutions designed to meet the demands of modern telecommunications infrastructures. With their advanced synchronization technologies, versatile connectivity options, and robust performance characteristics, these devices are essential components for ensuring accurate timekeeping in any network. Whether organizations choose the feature-rich 5402 or the cost-effective 5401, they can be confident in the reliability and precision these products deliver.
