SY10EL15ZC-TR

Clock Buffers, Drivers Overview

The SY10EL15ZC-TR is a low skew 1:4 clock distribution chip from the Precision Edge series, designed for high-speed system clocking. It accepts differential or single-ended ECL/PECL inputs and features a multiplexed clock input to support lower speed scan or test clocks alongside the primary system clock. The device includes a synchronous enable function to prevent runt clock pulses during state transitions. Packaged in a 16-pin SOIC (Z16-2) with tape and reel delivery, it operates within a commercial temperature range of 0°C to +85°C.

Clock Buffers, Drivers Feature Summary

• 50ps output-to-output skew for precise timing alignment
• Multiplexed clock input allowing selection between differential CLK and SCLK
• Synchronous enable/disable control to avoid runt clock generation
• 75KΩ internal input pull-down resistors on the SEL pin

Clock Buffers, Drivers Applications

• Low skew clock distribution networks
• High-speed system clock routing
• Scan or test clock distribution integration

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix 'ZCTR' confirms the 16-pin SOIC package and tape and reel packaging format. Confirm that the 'ZC' designation aligns with the required commercial operating temperature range of 0°C to +85°C. Ensure the component meets RoHS requirements if applicable, noting that Pb-Free variants utilize the 'ZG' suffix instead.

Clock Buffers, Drivers Selection Notes

Select this component when a 1:4 fanout with minimal skew is required. The multiplexed input allows integration of test clocks without additional hardware. Verify power supply compatibility, as the device requires VEE between -4.75V and -5.5V for the 10EL series. Ensure the application can accommodate the differential or single-ended input configuration supported by the VBB reference pin.

Clock Buffers, Drivers Part Context

The SY10EL15 belongs to Micrel's Precision Edge family of low skew clock drivers. The 'SY10' prefix indicates the 10EL logic series, which typically operates with negative supply voltages. The 'ZC' suffix denotes the commercial temperature grade, while 'TR' specifies the tape and reel packaging method used for automated assembly.

Clock Buffers, Drivers Replacement Considerations

The SY100EL15ZC-TR serves as a direct functional replacement within the same package, offering identical specifications but supporting a wider VEE operating range of -4.2V to -5.5V.
