Overview
The SY10EP33VZI is a ÷4 PECL/LVPECL divider from the Precision Edge® ECL Pro™ family, manufactured by Microchip Technology. It operates with 3.3V and 5V power supply options and supports maximum frequencies exceeding 4GHz. The device features guaranteed propagation delay of less than 460ps over the operating temperature range of -40°C to +85°C. It includes internal 75kΩ input pull-down resistors and an asynchronous reset pin for synchronous system use. The component is housed in an 8-pin SOIC package.
Feature Summary
- Integrated divide-by-4 frequency division functionality
- Asynchronous reset capability for synchronized multi-device systems
- Internal reference voltage generation (VBB) for AC-coupled inputs
- Built-in input pull-down resistors for stability
Applications
- High-speed clock distribution networks
- Frequency synthesis circuits
- Telecommunications infrastructure
- Data center interconnects
Procurement Notes
Verify that the ordering suffix 'ZI' corresponds to the Industrial temperature range (-40°C to +85°C) and the Z8-1 (SOIC-8) package type as specified in the manufacturer's ordering information. Confirm lead finish specifications if RoHS compliance or specific solderability requirements are necessary for the assembly process.
Selection Notes
Select this component when a high-frequency divider exceeding 4GHz is required within industrial temperature constraints. Ensure the design accommodates the VBB pin requirements, specifically decoupling via a 0.01µF capacitor if used for rebiasing AC-coupled inputs. Verify compatibility with PECL or LVPECL logic levels based on the chosen supply voltage.
Part Context
This part belongs to the SY10/100EP33V series of integrated dividers utilizing Micrel's Precision Edge technology. The '10EP' designation indicates compatibility with positive ECL 10H logic levels, distinguishing it from the '100EP' variant which aligns with 100K logic levels. The 'ZI' suffix specifically denotes the industrial grade and surface-mount packaging configuration.

FAQ
How should the VBB pin be handled if not used for single-ended input conditions?
If the VBB pin is not utilized for rebiasing AC-coupled inputs or providing a switching reference voltage, it should be left open.
What is the function of the RESET pin?
The RESET pin provides an asynchronous reset function that is asserted on the rising edge, allowing for the synchronous use of multiple EP33 devices in a system.
