Limited Warranty

Each new product manufactured by Symmetricom is warranted for defects in material or workmanship for a period of one year from date of shipment (“Limited Warranty”). Defects in material or workmanship found within that period will be replaced or repaired, at Symmetricom’s option, without charge for material or labor, provided the customer returns the equipment, freight prepaid, to the Symmetricom factory under this limited warranty. Symmetricom will return the repaired equipment, freight prepaid, to the customer’s facility. This one year Limited Warranty does not apply to any software or to any product not manufactured by Symmetricom.

If on-site warranty repair or replacement is required, the customer will be charged the then current field service rate for portal-to-portal travel time plus actual portal-to-portal travel charges. There is no charge for on-site warranty repair labor.

Products not manufactured by Symmetricom, but included as integral part of a system (e.g., peripherals, options), are warranted for 90 days, or longer as provided by the original equipment manufacturer, from date of shipment.

Aside from the Limited Warranty set forth above, Symmetricom makes no other warranties, express or implied, of merchantability, fitness for purpose or of any other kind or description whatsoever.

By purchasing any product manufactured by Symmetricom, the buyer consents to and agrees with Symmetricom that as a result of the exclusion of all warranties, expressed or implied, of merchantability, fitness for purpose, or otherwise, except for the limited one-year warranty for defects in material and workmanship for products manufactured by Symmetricom, that the Buyer has the sole responsibility to assess and bear all losses relating to (1) the ability of the product or products purchased to pass without objection under the contract description among merchants and buyers in the trade; (2) the conformity of the product or products to fair average quality within its contract description; (3) the fitness of the product for the ordinary purposes for which such product is used; (4) the consistency of quality and quantity within each unit of product or products and among all units involved; (5) the adequacy of containers, packaging and labeling of the product or products; (6) the conformity of the product, promises or affirmations of fact (if any) made on its label or container; and (7) the conformity of the product to standards of quality observed by other merchants in the trade with respect to products of similar description.

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.
