SY10E446JC-TR

Specialized Overview

The SY10E446JC-TR is a 4-bit parallel-to-serial data converter manufactured by Microchip Technology. It operates with NRZ data rates up to a minimum of 1.3 Gb/s and features a typical capability of 1.6 Gb/s. The device includes on-chip clock dividers for divide-by-4 and divide-by-8 outputs, supporting both standalone 4-bit conversion and cascaded 8-bit configurations. It utilizes differential serial and clock inputs, with an extended VEE range from -4.2V to -5.5V. The component is housed in a 28-pin PLCC package.

Specialized Feature Summary

• Integrated 4-bit parallel-to-serial data conversion with asynchronous synchronization
• On-chip divide-by-4 and divide-by-8 clock generation capabilities
• Supports cascading two devices for 8-bit conversion via serial input/output
• Extended negative supply voltage range for ECL compatibility

Specialized Applications

• High-speed serial data path transmission systems
• Cascaded multiplexer architectures requiring 8:1 conversion
• Clock distribution networks utilizing internal divided clocks

Specialized Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation to confirm tape and reel packaging and lead finish specifications. Ensure the component version matches the required commercial operating temperature range and electrical characteristics defined in the official datasheet before integration into production designs.

Specialized Selection Notes

Select this component when designing high-speed serial links requiring parallel-to-serial conversion at frequencies up to 1.6 Gb/s. Consider the cascading architecture if 8-bit conversion is necessary, noting that clock edge alignment techniques may be required to maintain maximum throughput in multi-device setups.

Specialized Part Context

This part belongs to the SY10/100E446 family of integrated parallel-to-serial converters. It is fully compatible with the Motorola MC10E/100E446 specifications. The device is designed to operate alongside complementary components like the E445 receiver to establish complete high-speed serial communication paths.

Specialized Replacement Considerations

The SY10E446JC-TR is fully compatible with the Motorola MC10E446. Verify pinout and electrical parameters against the original design requirements when substituting.
