SY89835UMG-TR

Clock Buffers, Drivers Overview

The SY89835UMG-TR is a high-speed, differential 1:2 LVDS fanout buffer operating on a 2.5V ±5% supply. It supports DC-to >3.2 Gbps throughput with a typical propagation delay of 210ps and guaranteed within-device skew under 20ps. The device features ultra-low jitter performance (<1ps RMS cycle-to-cycle) and includes internal 100Ω input termination. A Fail-Safe Input (FSI) mechanism prevents metastable output oscillation when the input signal amplitude drops below 100mV or during clock failure.

Clock Buffers, Drivers Feature Summary

• Guaranteed AC performance over temperature and voltage with <20ps within-device skew
• Fail-Safe Input (FSI) protection to latch outputs during low-swing or missing input signals
• Ultra-low jitter design: <1ps RMS random jitter and <10ps PP total jitter
• Internal 100Ω differential input termination for simplified interface

Clock Buffers, Drivers Applications

• Clock or data distribution networks
• SONET clock or data distribution
• Fibre Channel clock or data distribution
• Gigabit Ethernet clock or data distribution

Clock Buffers, Drivers Procurement Notes

Verify that the component matches the Micrel datasheet specifications for the SY89835U series. Confirm the package type is MLF-8 and the operating range covers the industrial temperature span from –40°C to +85°C. Ensure the ordering suffix corresponds to the tape and reel configuration as indicated in the manufacturer's documentation.

Clock Buffers, Drivers Selection Notes

Select this component for applications requiring ultra-low skew and jitter in differential LVDS environments. The internal termination simplifies PCB layout by removing external resistors. Verify that the system operates within the 2.375V to 2.625V supply voltage range and that the input signal swing meets the minimum threshold for proper FSI operation if required.

Clock Buffers, Drivers Part Context

The SY89835U belongs to Micrel’s Precision Edge family of high-speed clock synchronization devices. This specific part number represents the tape and reel version of the 8-pin MLF packaged buffer. It is designed to complement other components in the same family, such as multiplexers and translators, for comprehensive clock tree solutions.
