SY88933ALKG-TR

Overview

The SY88933ALKG-TR is a high-sensitivity limiting post amplifier designed for fiber-optic receivers. It operates on a single 3.3V supply and connects to typical transimpedance amplifiers (TIAs). The device quantizes noisy linear signal outputs from TIAs, which may vary in amplitude over time, and outputs PECL level waveforms. Key electrical parameters include a voltage gain of 42 dB, a maximum supply voltage of 5.5 V, and a minimum supply voltage of 3 V. The operating supply current is 26 mA. It functions within a temperature range of -40°C to +85°C and is housed in a 10-pin MSOP package.

Feature Summary

• Designed specifically for use in fiber-optic receivers to process signals from transimpedance amplifiers
• Quantizes noisy linear signal outputs that may vary in amplitude over time
• Outputs PECL level waveforms for downstream processing
• Operates on a single 3.3V supply with low power consumption

Applications

• Fiber-optic receiver signal conditioning
• Post-amplification for transimpedance amplifier outputs
• PECL waveform generation in optical communication systems

Procurement Notes

Verify the specific suffix KG-TR against the manufacturer's official datasheet to confirm the reel packaging configuration and tape-and-reel quantity. Ensure the 3.3V supply requirement aligns with your system design, as the device supports a range up to 5.5V but is optimized for 3.3V operation. Confirm moisture sensitivity levels and reflow soldering profiles if applicable to your manufacturing process.

Selection Notes

Select this component when interfacing with transimpedance amplifiers in fiber-optic applications requiring PECL output. It is suitable for designs needing high sensitivity and noise quantization. Consider the 10-pin MSOP package size for space-constrained PCB layouts. Verify that the 42 dB gain meets the system's dynamic range requirements before finalizing the design.
