SY10EP16UZG-TR

Overview

The SY10EP16UZG-TR is a high-speed, fully differential ECL Receiver/Driver from the Precision Edge series. It processes clock signals up to 3GHz or data patterns up to 2.5Gbps with a typical propagation delay of 240ps and rise/fall times under 200ps. The device operates on a 2.5V ±5% or 3.3V ±10% supply (PECL mode) or -2.375V to -3.63V (NECL mode). It features an integrated voltage reference (VBB), internal pull-down/up resistors, and ultra-low jitter (<0.3ps RMS random jitter). Packaged in SOIC-8, it supports industrial temperatures from –40°C to +85°C.

Feature Summary

• Supports PECL and NECL operation modes for flexible power supply configurations
• Includes an integrated VBB reference output for single-ended biasing and AC-coupled termination
• Features internal input clamps that force the Q output low when inputs are left open
• Provides fast rise and fall times guaranteed to be less than 200ps

Applications

• SONET clock and data distribution
• Fibre Channel clock and data distribution
• Gigabit Ethernet clock and data distribution
• Backplane distribution

Procurement Notes

Verify the specific suffix 'TR' indicates tape and reel packaging rather than tube. Confirm the '10EP' designation matches the required 10K ECL compatible I/O specifications, as opposed to the 100K variant. Ensure the SOIC-8 package type aligns with board layout requirements. Check current availability status as this component may have lifecycle changes.

Selection Notes

Select this part for applications requiring precise differential signal translation between ECL logic families. It is suitable for designs needing an integrated reference voltage to simplify single-ended interface circuits. Consider the thermal resistance of the SOIC-8 package for heat dissipation needs within the specified operating temperature range.

FAQ

How should the VBB pin be utilized?

The VBB pin provides an integrated voltage reference typically used to bias unused inverting inputs for single-ended applications or as a termination point for AC-coupled differential inputs. It must be bypassed to the most positive supply voltage.

What happens if the inputs are left open?

Internal input clamps will force the Q output low whenever the differential inputs are left unconnected or open.
