SCAN25100TYAX/NOPB

Serializers, Deserializers Overview

The SCAN25100TYAX/NOPB is a serializer/deserializer (SerDes) integrated circuit designed for Common Public Radio Interface (CPRI) applications. It supports data rates of 2457.6 Mbps, 1228.8 Mbps, and 614.4 Mbps. The device features a 10-to-1 serialization configuration with LVCMOS/LVTTL inputs and an LVDS output. It includes auto rate resynchronization and precision delay calibration measurement capabilities. Powered by 1.8V and 3.3V supplies, it operates within a temperature range of -40°C to 85°C and is housed in a 100-HTQFP package.

Serializers, Deserializers Procurement Notes

Verify component authenticity through authorized channels as the part is discontinued. Confirm package integrity and moisture sensitivity level handling procedures before assembly. Check for obsolescence notices from Texas Instruments or National Semiconductor legacy records. Ensure supply chain documentation matches the specific SCAN25100TYAX/NOPB designation.

Serializers, Deserializers Selection Notes

Select this component for CPRI-compliant baseband unit interfaces requiring specific serialization ratios. Compare against newer SerDes families if long-term availability is critical. Verify voltage domain compatibility between 1.8V and 3.3V rails in the target design. Assess thermal performance requirements for the HTQFP enclosure in enclosed environments.

Serializers, Deserializers Part Context

This component belongs to the SCAN25100 series originally developed by National Semiconductor and later maintained by Texas Instruments following their acquisition. The series addresses high-speed serial communication needs in wireless infrastructure. The NOPB suffix indicates a lead-free, environmentally compliant variant of the original SCAN25100TYA part number.

Serializers, Deserializers Replacement Considerations

Publicly confirmed substitutes include the SCAN25100TYA and SCAN25100TYA/NOPB. These variants share identical functional specifications and pinouts. Verify package compatibility when transitioning between these specific part numbers.
