SY10E446JC

Specialized Overview

The SY10E446JC is a 4-bit parallel-to-serial data converter manufactured by Microchip Technology. It operates with a typical maximum conversion frequency of 1.6 Gb/s and supports NRZ data rates up to 1.3 Gb/s minimum. The device features on-chip divide-by-4 and divide-by-8 clock outputs, differential serial and clock inputs, and an asynchronous SYNC input for resetting the internal clock circuitry. It functions in 4-bit mode or cascades for 8-bit conversion via its MODE pin. Power supply requirements include VEE ranging from -4.2V to -5.5V, with VCC and VCCO at ground potential. The component is housed in a 28-pin PLCC package.

Specialized Feature Summary

• Integrated divide-by-4 and divide-by-8 clock generation for flexible timing control
• Differential serial data input and output supporting high-speed NRZ transmission
• Asynchronous synchronization input for resetting the internal clock conversion unit
• Mode select capability to expand functionality to 8-bit conversion using two devices

Specialized Applications

• High-speed parallel-to-serial data conversion for telecommunications systems
• Cascaded 8:1 multiplexer architectures utilizing dual E446 devices
• Clock distribution networks requiring divided reference signals

Specialized Procurement Notes

Verify the manufacturer origin carefully, as the datasheet identifies Micrel, Inc. as the original designer while Microchip Technology lists it under their portfolio. Confirm that the specific ordering suffix matches the required lead finish and packaging type. Ensure compatibility with existing system voltage levels before procurement.

Specialized Selection Notes

Select this component when designing high-speed serial links requiring parallel-to-serial conversion. Consider the extended VEE range if operating in environments with negative supply variations. Evaluate the propagation delay specifications against your system's timing budget, particularly for cascaded configurations where setup times are critical.

Specialized Part Context

This part belongs to the 100E series of high-speed logic components originally developed by Micrel. It serves as a specialized interface chip for converting parallel data streams into serialized formats suitable for long-distance transmission. The device complements other series members like the E445 receiver to form complete data path solutions.

Specialized Replacement Considerations

The datasheet states full compatibility with the Motorola MC10E/100E446. Verify pinout and electrical characteristics match exactly before substituting. No other direct substitutes are documented in the provided source material.
