SY10E445JZ-TR

Specialized Overview

The SY10E445JZ-TR is a 4-bit serial-to-parallel data converter manufactured by Microchip Technology. It operates with NRZ data rates up to 2.5Gb/s and supports an extended 100E VEE range of –4.2V to –5.5V. The device features differential clock and serial inputs, on-chip clock ÷4 and ÷8 outputs, and asynchronous data synchronization via the SYNC input. It includes internal 75kΩ input pull-down resistors and a MODE pin for expanding conversion to 8 bits using two devices. The component is housed in a 28-pin PLCC package.

Specialized Feature Summary

• Integrated 4-bit serial-to-parallel data conversion capability
• On-chip divide-by-4 and divide-by-8 clock generation
• Asynchronous data synchronization and loopback testing support

Specialized Applications

• High-speed serial data path receiving systems
• Cascaded 1:8 demultiplexer architectures
• Loop test architecture for electrical link verification

Specialized Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm lead finish and packaging type. The 'TR' suffix indicates tape and reel packaging. Confirm RoHS compliance status and moisture sensitivity levels prior to procurement. Ensure the source document matches the exact part number to avoid discrepancies in electrical characteristics or pinout definitions.

Specialized Selection Notes

Select this component for applications requiring high-speed serial-to-parallel conversion up to 2.5Gb/s. Consider the 28-pin PLCC package constraints and the need for differential signaling at clock rates above 500MHz. Evaluate the cascading requirements if an 8-bit conversion scheme is necessary, as this impacts the maximum operating frequency.

Specialized Part Context

The SY10E445 belongs to the Micrel (now Microchip) 10E/100E ECL logic family. It is fully compatible with the Motorola MC10E/100E445. The device is designed to work in conjunction with the E446 parallel-to-serial converter to provide complete transmission and receiving solutions for high-speed serial data paths.

Specialized Replacement Considerations

The device is fully compatible with the Motorola MC10E/100E445. Verify pinout and electrical specifications before substituting with other serial-to-parallel converters from different manufacturers.

Specialized FAQ

How does the SYNC input affect the conversion sequence?

Asserting the SYNC input asynchronously shifts the start bit for conversion from Qn to Qn-1 by one bit. Each additional pulse required shifts the start bit further.

What is the purpose of the MODE input?

The MODE input selects the conversion mode. When LOW, the device functions as a 4-bit converter. When HIGH, it allows for an 8-bit conversion scheme using two E445 devices.

Can the SY10E445 be used for loopback testing?

Yes, the device provides multiplexed dual serial inputs that enable a loopback capability when used in conjunction with the E446 parallel-to-serial converter.
