SY54016ARMG-TR

Overview

The SY54016ARMG-TR is a fully-differential, low-voltage CML line driver and receiver manufactured by Microchip Technology. It supports data rates up to 3.2 Gbps and clock frequencies of 3.2 GHz. The device operates with a 2.5V ±5% core supply (VCC) and an output supply (VCCO) of either 1.8V or 1.2V ±5%. It features guaranteed AC performance including propagation delays under 280ps and rise/fall times below 95ps. The component is housed in an 8-pin MLF package measuring 2mm x 2mm.

Feature Summary

• Accepts differential input signals as small as 100mV without external level-shifting or termination resistor networks.
• Features ultra-low jitter design with less than 1ps RMS random jitter.
• Includes an internal voltage reference on the VT pin to facilitate AC-coupled input interface applications.

Applications

• OC-48 and OC-48+FEC data distribution
• SONET clock and data distribution
• Fibre Channel clock and data distribution
• Gigabit Ethernet clock and data distribution

Procurement Notes

Verify that the ordering suffix matches the specific package type and lead finish requirements for your assembly process. Confirm the operating temperature range aligns with your system's environmental specifications. Ensure power supply decoupling capacitors are placed close to the VCC and VCCO pins as recommended in the datasheet interface applications section.

Selection Notes

Select this component when interfacing between LVPECL, LVDS, or CML sources and CML destinations. It is suitable for high-speed signal transmission where minimal jitter and fast edge rates are critical. Consider the dual-supply architecture if your system requires distinct core and output voltage levels.

Part Context

This part belongs to Micrel’s Precision Edge product line, now under Microchip Technology. It is designed for high-speed digital communication systems requiring reliable differential signaling. The device replaces older discrete solutions by integrating termination and buffering functions into a compact surface-mount package.

Replacement Considerations

The SY54016R is listed as a related product with similar 3.2Gbps capabilities but may differ in specific buffer configurations or fail-safe input features. Verify functional block diagrams and electrical characteristics before substitution.

FAQ

How should the VT pin be handled for AC-coupled inputs?

For AC-coupled inputs, bypass the VT pin with a 0.1µF low ESR capacitor connected to VCC. The pin provides an internal high-impedance bias voltage for the input stage.

What is the recommended output termination for a 1.2V VCCO supply?

When VCCO is 1.2V, terminate the outputs with 50Ω to 1.2V in a DC-coupled configuration. Do not use 100Ω differentially across the outputs in this specific voltage scenario.
