Overview
The SY89250VMI-TR is a Precision Edge differential PECL/ECL receiver and buffer manufactured by Microchip Technology. It operates on 3.3V or 5V power supplies with an operating temperature range of -40°C to +85°C. The device features a 250ps propagation delay, very high voltage gain, and data-synchronous enable/disable functionality for glitchless gating. It is housed in an ultra-small 8-pin MLF package measuring 2mm x 2mm.
Feature Summary
- Provides data-synchronous Enable/Disable (/EN) input for complete glitchless gating of QHG and /QHG outputs
- Features a VBB output serving as DC bias for AC-coupling or single-ended applications
- Offers very high voltage gain suitable for pulse amplifier and limiting amplifier applications
- Designed for crystal oscillator modules requiring free-running oscillation with synchronous gating
Applications
- Oscillator modules
- Pulse amplifier circuits
- Limiting amplifier applications
- High frequency crystal oscillator designs
Procurement Notes
Verify the specific ordering suffix 'MI' corresponds to the industrial temperature range (-40°C to +85°C) and MLF-8 package type. Confirm that the 'TR' designation indicates tape and reel packaging. Ensure compatibility with 3.3V or 5V supply requirements and check for RoHS compliance status relative to the lead finish specifications.
Selection Notes
Select this component when a compact differential receiver with synchronous gating is required. It serves as a functional equivalent to the SY100EL16VC but occupies a significantly smaller footprint. Consider its suitability for applications needing glitch-free signal control and high voltage gain within space-constrained PCB layouts.
Part Context
This part belongs to the Precision Edge family of high-speed logic devices from Micrel, now under Microchip Technology. It is designed to replace larger footprint components like the SY100EL16VC while maintaining similar electrical performance characteristics for PECL and ECL interface applications.
Replacement Considerations
The SY89250V is functionally equivalent to the SY100EL16VC. Verify pinout compatibility and ensure the replacement supports the required 3.3V or 5V supply voltages and operating temperature ranges.
