SY58052UMG TR

Clock Generators, PLLs, Frequency Synthesizers Overview

The SY58052UMG TR is an ultra-fast, precision, low-jitter data-to-clock resynchronizer manufactured by Micrel (now Microchip Technology). It guarantees AC performance over temperature and voltage with a DC-to >10.7Gbps data rate throughput and DC-to >7GHz clock fMAX. The device features <190ps any in-to-out propagation delay and rise/fall times under 60ps. It incorporates internal 50Ω input and output source termination, supporting 400mV CML output swing. Operating from a 2.5V ±5% or 3.3V ±10% supply, it functions within the -40°C to +85°C industrial temperature range.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Ultra-low jitter design: <1ps RMS random jitter, <10ps PP deterministic jitter, and <10ps PP total jitter for clock applications.
• Internal 50Ω input and output termination with unique VT pins accepting both DC- and AC-coupled inputs (CML, PECL).
• Guaranteed high-speed performance: DC-to >10.7Gbps data rate and DC-to >7GHz clock frequency.
• TTL/CMOS-compatible /RESET input for asynchronous control of the Q output state.

Clock Generators, PLLs, Frequency Synthesizers Applications

• Data communication systems requiring backplane retiming or retiming after long trace lengths.
• Serial OC-192 and OC-192+FEC data-to-clock realignment.
• Parallel 10Gbps applications for OC768 standards.
• SONET OC-3 through OC-768 applications.
• Fibre Channel and Gigabit Ethernet (GigE) implementations.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify that the ordering suffix 'TR' corresponds to the Tape and Reel packaging format as specified in the manufacturer's documentation. Confirm the Pb-Free status associated with the 'G' suffix if required for new designs. Ensure compatibility with the MLF-16 package dimensions and thermal requirements, specifically connecting the exposed pad to ground for proper heat dissipation.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a precision data-to-clock resynchronizer with guaranteed low jitter is required for speeds up to 10.7Gbps. The internal termination simplifies interface design for CML and PECL signals without external resistors. Consider the 2.5V or 3.3V supply options and the industrial temperature range (-40°C to +85°C) for suitability in harsh environments. Verify input signal compatibility with the internal 50Ω termination network via the VT pins.
