Overview
The SY100EP33VZI is a ÷4 PECL/LVPECL divider from the Precision Edge series. It supports 3.3V and 5V power supplies with a guaranteed maximum frequency exceeding 4GHz. Propagation delay remains under 460ps across the operating temperature range of -40°C to +85°C. The device features internal 75kΩ input pull-down resistors and an asynchronous reset pin. It is housed in an 8-pin SOIC package.
Feature Summary
- Integrated divide-by-4 clock divider functionality
- Internal VBB reference voltage generation for AC-coupled inputs
- Asynchronous reset capability for synchronous system use
- Temperature-compensated circuitry within the 100K Series
Applications
- High-speed clock distribution networks
- Frequency division in RF systems
- Synchronization circuits requiring precise timing control
Procurement Notes
Verify the specific suffix ZI confirms the industrial temperature range (-40°C to +85°C) and 8-pin SOIC package type. Confirm lead finish specifications against current manufacturing standards, as original datasheets may list legacy finishes. Ensure compatibility with existing PCB footprints before finalizing procurement orders.
Selection Notes
Select this component when a high-frequency divide-by-4 function is required for PECL or LVPECL logic families. The integrated VBB pin simplifies biasing for AC-coupled differential inputs. Verify that the 460ps propagation delay meets the system's timing constraints and that the 8-pin SOIC package fits the available board space.
Part Context
This part belongs to the SY10/100EP33V family manufactured originally by Micrel, now Microchip Technology. The '100' prefix indicates the 100K Series with internal temperature compensation. The 'ZI' suffix denotes the industrial temperature range and the 8-pin SOIC package configuration.

FAQ
How should the unused differential input be handled?
For single-ended input conditions, connect the unused differential input to the VBB pin to serve as a switching reference voltage.
What is the function of the VBB pin?
The VBB pin provides an internally-generated voltage supply used to rebias AC-coupled inputs or act as a reference for single-ended operation.
