SY89826LHY-TR

Clock Buffers, Drivers Overview

The SY89826LHY-TR is a Precision Edge 1:22 LVDS fanout buffer/translator manufactured by Microchip Technology (originally Micrel). It operates on a single 3.3V supply and accepts either LVDS or LVPECL inputs via a 2:1 multiplexer controlled by the CLK_SEL pin. The device provides 22 differential LVDS output pairs with guaranteed AC parameters over temperature and voltage, including a maximum toggle frequency exceeding 1GHz. Key performance metrics include within-device skew of less than 50ps, cycle-to-cycle jitter under 1ps RMS, and total jitter under 1ps peak-to-peak. It is housed in a 64-pin EPAD-TQFP package.

Clock Buffers, Drivers Feature Summary

• 1GHz Maximum Toggle Frequency with <50ps within-device skew
• Low Jitter Performance: <1ps RMS cycle-to-cycle and <1ps pk-pk total jitter
• 2:1 Input Mux supporting both LVDS (with internal 100Ω termination) and LVPECL inputs
• Synchronous Output Enable (OE) function to prevent runt clock pulses

Clock Buffers, Drivers Applications

• Enterprise networking equipment
• High-end servers
• Communications infrastructure

Clock Buffers, Drivers Procurement Notes

Verify that the specific ordering suffix 'HY' corresponds to the Pb-Free Matte-Sn finish as defined in the manufacturer's ordering information table. Confirm the 'TR' suffix indicates Tape and Reel packaging. Ensure compatibility with the 64-Pin EPAD-TQFP (H64-1) package dimensions for PCB layout.

Clock Buffers, Drivers Selection Notes

Select this component when a high-output count (22 pairs) with ultra-low skew is required for 3.3V systems. Ensure input signals match the selected mux configuration (LVDS vs. LVPECL). Unused output pairs must be terminated with 100Ω resistors to maintain specified skew and jitter performance. Verify thermal requirements for the exposed pad TQFP package based on airflow conditions.

Clock Buffers, Drivers Part Context

The SY89826L belongs to the Precision Edge family of high-performance clock buffers. While originally developed by Micrel, Inc., the product line is now managed by Microchip Technology. The 'HY' variant specifically denotes the lead-free version with matte tin plating, distinct from the standard Sn-Pb versions like the SY89826LHI.
