SY100EP16UZG-TR

Specialty Logic Overview

The SY100EP16UZG-TR is a high-speed, fully differential ECL Receiver/Driver from the Precision Edge family. 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 in PECL mode (VEE = 0V) or NECL mode (VCC = 0V). It features an integrated voltage reference (VBB), internal input pull-down/up resistors, and ultra-low jitter design (< 0.3ps RMS random jitter). Packaged in SOIC-8, it supports industrial temperature ranges (-40°C to +85°C).

Specialty Logic Feature Summary

• Supports AC-coupled differential inputs and single-ended applications via an integrated VBB bias pin.
• 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 for high-speed signal integrity.

Specialty Logic Applications

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

Specialty Logic Procurement Notes

Verify the specific suffix 'ZG' confirms the SOIC-8 package type and lead finish details against official manufacturer documentation. Confirm the '-TR' designation indicates tape and reel packaging. Ensure the component matches the 100K ECL compatible I/O specification rather than the 10K variant. Check current availability status as this part may have lifecycle changes.

Specialty Logic Selection Notes

Select this component for designs requiring precise 800mV ECL swing drivers with minimal jitter. It is suitable for systems needing both PECL and NECL operation capabilities within a single package. Consider the internal 75kΩ pull-down and 37.5kΩ pull-up resistors if interfacing with standard transmission lines without external termination components.

Specialty Logic Part Context

This device belongs to Micrel's Precision Edge product line, now under Microchip Technology. It is part of the SY10/100EP16U series, which differentiates between 10K and 100K ECL compatible I/O speeds. The SY100EP16U specifically targets higher speed requirements compared to its 10EP counterpart.

Specialty Logic FAQ

How should the VBB pin be used?

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?

When the inputs are left open, the internal input clamps will force the Q output low.
