SY89830UK4I

Clock Buffers, Drivers Overview

The SY89830UK4I is a high-speed, differential PECL 1:4 fanout buffer with an integrated 2:1 input multiplexer. It supports maximum frequencies up to 2.5GHz and guarantees within-device skew of less than 25ps across the operating temperature range. The device operates on flexible supply voltages including 2.5V, 3.3V, and 5V. Key electrical parameters include propagation delays ranging from 275ps to 450ps depending on logic family and input swing, and cycle-to-cycle jitter below 1ps RMS. It features synchronous enable functionality and accepts PECL, LVPECL, ECL, LVECL, and HSTL input levels.

Clock Buffers, Drivers Feature Summary

• Ultra-low within-device skew guaranteed at less than 25ps
• Flexible power supply operation supporting 2.5V, 3.3V, and 5V systems
• Synchronous enable pin prevents runt clock pulses during state changes

Clock Buffers, Drivers Applications

• Redundant clock switchover systems
• High-speed data distribution networks
• Clock buffering in telecommunications infrastructure

Clock Buffers, Drivers Procurement Notes

Verify that the ordering suffix 'I' corresponds to the industrial temperature grade (-40°C to +85°C) as specified in the manufacturer's documentation. Confirm package type is TSSOP-16. Ensure lead finish requirements match the specific variant (Sn-Pb or NiPdAu). Cross-reference the full part number against official distributor catalogs to confirm current availability status.

Clock Buffers, Drivers Selection Notes

Select this component when low skew and high-frequency performance are critical. The internal 2:1 MUX simplifies designs requiring clock redundancy without external switching components. Verify that the system voltage aligns with the supported 2.5V, 3.3V, or 5V rails. Consider the synchronous enable feature if glitch-free clock switching is required during transitions.

Clock Buffers, Drivers Part Context

This device belongs to Micrel’s Precision Edge timing and distribution family, now under Microchip Technology. It serves as a specialized clock driver designed for precision edge applications where signal integrity and minimal skew are paramount. The inclusion of both buffering and multiplexing capabilities consolidates multiple functions into a single package.

Clock Buffers, Drivers Replacement Considerations

Consult the manufacturer's product line for alternative I/O combinations or package types. Specific cross-references should be validated against the latest datasheet to ensure functional compatibility regarding voltage levels and speed grades.
