SY88063CLMG

Special Purpose Amplifiers Overview

The SY88063CLMG is a limiting post amplifier designed for fiber-optic receivers in multi-rate applications ranging from 1.0625Gbps to 12.5Gbps. It operates on a single +3.3V power supply within an industrial temperature range of –40°C to +85°C. The device features user-programmable SD assert/LOS de-assert thresholds, selectable digital offset correction (DOC), and integrated 50Ω input/output impedances. It provides fast SD assert and LOS de-assert times with typical electrical hysteresis to minimize signal chattering.

• Supports multi-rate operation from 1.0625Gbps to 12.5Gbps with wide differential input voltage range
• Includes user-selectable digital offset correction to automatically compensate for internal device offsets
• Provides integrated 50Ω termination impedance at both low-noise CML data inputs and outputs
• Features TTL-compatible JAM input for SQUELCH function and selectable LOS or SD status indication

Special Purpose Amplifiers Applications

• Asymmetrical/Symmetrical 10GEPON
• Asymmetrical/Symmetrical XGPON
• 10Gigabit Ethernet
• 8Gbps and 10Gbps Fibre Channel
• SONET OC192/SDH STM64

Special Purpose Amplifiers Procurement Notes

Verify the specific package marking and lead finish requirements against the official datasheet before procurement. Confirm that the selected variant matches the required operating temperature range and power supply specifications. Ensure compatibility with the intended PCB layout regarding the exposed thermal pad connection. Review the absolute maximum ratings to prevent device damage during installation and operation.

Special Purpose Amplifiers Selection Notes

Select this component when designing fiber-optic receiver circuits requiring high sensitivity and bandwidth up to 12.5Gbps. Consider the integrated 50Ω terminations to reduce external component count and optimize signal paths. Evaluate the programmable threshold levels and DOC functionality for optimizing system reach and minimizing output offsets in noisy environments.
