SY89206VMG-TR

Overview

The SY89206VMG-TR is a differential PECL/ECL receiver and buffer manufactured by Microchip Technology. It operates with 3.3V or 5V power supplies and supports maximum frequencies exceeding 1.0 GHz. The device features a typical propagation delay of 250 ps, an output reference voltage (VBB) for AC coupling bias, and internal 75 kΩ input pull-down resistors. It is housed in an ultra-small 8-pin 2 mm x 2 mm DFN package and functions within an industrial temperature range of –40°C to +85°C.

Feature Summary

• Supports both 3.3V and 5V power supply configurations
• Includes an integrated VBB pin for single-ended use or AC-coupling bias
• Features internal 75 kΩ input pull-down resistors that force the Q output LOW under open input conditions

Applications

• High-speed differential signal buffering
• PECL/ECL interface translation
• Datacom and telecommunications equipment

Procurement Notes

Verify the specific ordering suffix 'TR' indicates tape and reel packaging containing 1,000 units per reel. Confirm the 'M' package designation corresponds to the 8-Lead DFN form factor. Ensure the 'G' suffix matches the specified industrial temperature range of –40°C to +85°C. Cross-reference the datasheet revision B for updated common mode range specifications before finalizing procurement documentation.

Selection Notes

Select this component when a compact footprint is required for high-frequency differential signaling. The device serves as a functional equivalent to the SY100EL16V but offers a significantly smaller physical size. Consider the internal pull-down resistors for simplified input handling and utilize the VBB pin to streamline AC-coupling designs without external bias networks.

Part Context

This part belongs to the SY89 series of high-speed logic devices from Microchip Technology. It is derived from Micrel's Precision Edge product line, which focuses on low jitter and high bandwidth performance. The SY89206V specifically targets applications requiring small form factors alongside robust PECL and ECL compatibility standards.

Replacement Considerations

The SY100EL16V is documented as functionally equivalent but occupies a larger footprint. Verify pinout compatibility and electrical characteristics against current design requirements before substituting.
