SY89306VMG-TR

Overview

The SY89306VMG-TR is a high-speed differential buffer/receiver from Microchip Technology, operating at frequencies up to 2.5 GHz. It supports 3.3V and 5V power supplies with a typical supply current of 48 mA. The device features a propagation delay of 100 ps (typical) and operates within an industrial temperature range of -40°C to +85°C. Packaged in an ultra-small 8-lead DFN (2 mm x 2 mm), it includes internal 75 kΩ input pull-down resistors and a VBB reference pin for AC-coupling applications.

Feature Summary

• Supports differential PECL/ECL signaling with integrated 75 kΩ input pull-down resistors
• Includes a dedicated VBB reference voltage output for single-ended AC-coupling configurations
• Provides functional equivalence to legacy buffers while significantly reducing footprint size

Applications

• High-speed clock distribution networks
• Differential signal buffering in telecommunications equipment
• Data acquisition systems requiring PECL/ECL compatibility

Procurement Notes

Verify the specific ordering suffix 'TR' indicates tape and reel packaging containing 1,000 units per reel. Confirm that the 'MG' designation corresponds to the 8-lead DFN package with the specified industrial temperature range. Ensure compliance with RoHS standards by checking for the Matte Tin lead finish indicator on the outer packaging.

Selection Notes

Select this component when a compact differential receiver is required for PECL or ECL interfaces. The inclusion of internal pull-down resistors simplifies input termination design. Verify that the 2.5 GHz maximum frequency meets system requirements and that the 48 mA supply current fits within the available power budget.

Part Context

This device belongs to the SY89 series of high-speed logic components manufactured by Microchip Technology. It serves as a modern replacement for older generation buffers like the SY100EL16V, offering similar electrical performance in a much smaller physical package to support dense PCB layouts.
