SY89830UK4I-TR

Clock Buffers, Drivers Overview

The SY89830UK4I-TR is a high-speed, differential PECL 1:4 fanout buffer optimized for ultra-low skew applications. It features a 2:1 input MUX and operates within a supply voltage range of 2.5V to 5V. The device guarantees an fMAX greater than 2.5GHz, with within-device skew less than 25ps and propagation delay up to 450ps. It supports LVPECL, PECL, ECL, LVECL, and HSTL logic levels. Operating temperature ranges from –40°C to +85°C. It is housed in a 16-pin TSSOP package.

Clock Buffers, Drivers Procurement Notes

Verify the 'I' suffix confirms industrial temperature range (-40°C to +85°C) and the 'TR' suffix indicates tape and reel packaging. Confirm RoHS compliance status based on specific manufacturing lot requirements. Ensure proper termination resistors are used as specified in the datasheet for optimal signal integrity.

Clock Buffers, Drivers Selection Notes

Select this component when low jitter (<1ps RMS cycle-to-cycle) and minimal skew are critical. Use the integrated 2:1 MUX for redundant clock architectures. Ensure the design accommodates the required output swing and termination schemes for the chosen supply voltage (LVPECL, PECL, or ECL).

Clock Buffers, Drivers Part Context

This part belongs to Micrel’s Precision Edge family of high-speed timing and distribution components. It serves as a robust solution for distributing differential clock signals across complex digital systems while maintaining strict timing alignment between outputs.

Clock Buffers, Drivers Replacement Considerations

Consult the manufacturer's product line for alternative I/O combinations if different fan-out ratios or logic families are required. Verify pin compatibility before substituting with other devices in the SY89830U series.

Clock Buffers, Drivers FAQ

How does the synchronous enable pin function?

The /EN pin forces outputs into a fixed logic state only after the outputs are in a LOW state, eliminating the possibility of generating a "runt" clock pulse during switching.

What happens if only one input pair is used?

If only one input pair (IN0 or IN1) is utilized, the unused input pair may be left floating without affecting operation.

What is the typical within-device skew performance?

The device guarantees within-device skew to be less than 25ps over the full operating temperature and supply voltage range.
