SY54016RMG-TR

Overview

The SY54016RMG-TR is a fully differential, low voltage 1.2V/1.8V CML Line Driver/Receiver with Fail-Safe Input. It processes clock signals up to 2.5GHz or data patterns up to 3.2Gbps. The device operates from a 2.5V ±5% core supply and a 1.8V or 1.2V ±5% output supply. It features guaranteed AC performance over temperature and voltage, including less than 370ps propagation delay and less than 95ps rise/fall times. The component is available in an 8-pin (2mm x 2mm) MLF package and operates within the industrial temperature range of –40°C to +85°C.

Feature Summary

• Ultra-low jitter design with less than 1ps RMS random jitter for high-speed signal integrity.
• Unique 3-pin input termination architecture interfaces directly to LVPECL, LVDS, or CML signals without external level-shifting or termination resistor networks.
• Fail-safe input circuitry eliminates metastable conditions by latching the output to its last valid state when input amplitude drops below threshold.
• High-speed CML outputs provide extremely fast rise and fall times guaranteed to be less than 95ps.

Applications

• Data Distribution: OC-48, OC-48+FEC
• SONET clock and data distribution
• Fibre Channel clock and data distribution
• Gigabit Ethernet clock and data distribution

Procurement Notes

Verify the specific ordering suffix RMG-TR corresponds to the MLF-8 package type and tape and reel packaging configuration as documented in the official Microchip/Micrel ordering information. Confirm that the lead finish is NiPdAu Pb-Free and that the operating range matches the industrial specification of –40°C to +85°C. Ensure compatibility with the required 2.5V core and 1.2V/1.8V output supply voltages before procurement.

Selection Notes

Select this component for applications requiring differential line driving and receiving at speeds up to 3.2Gbps with minimal jitter. It is suitable for systems needing direct interface flexibility with LVPECL, LVDS, or CML sources without additional passive components. Consider the fail-safe feature for critical clock distribution where input signal loss must not cause undefined output states. Verify power supply constraints align with the dual-supply requirement of 2.5V core and 1.2V/1.8V output.

Part Context

The SY54016R belongs to Micrel’s Precision Edge product line, designed for high-speed, low-voltage applications. It functions as a line driver/receiver combining transmission and reception capabilities in a single differential channel. The device integrates internal termination and biasing mechanisms to simplify board layout and reduce component count in high-speed digital interfaces.

Replacement Considerations

The SY54016AR is listed as a related product with similar 3.2Gbps precision specifications and low voltage CML buffer functionality. Verify pinout compatibility and specific electrical characteristics against the SY54016AR datasheet before substitution.

FAQ

How does the Fail-Safe Input (FSI) function operate?

The FSI circuit senses the input signal amplitude. If the signal drops below approximately 30mV pk (200mV pp), it latches the output to its last valid state to prevent metastability or ringing caused by floating inputs.

What input signal types are supported without external termination?

The device supports LVPECL, LVDS, and CML differential signals as small as 100mV (200mV pp) due to its unique 3-pin input termination architecture, eliminating the need for external level-shifting or termination resistor networks.
