Datasheet Summary with AI

1. Overview

️· The SRC48 is a 24-pin receiver designed for OC-48/STM-16 applications. It converts optical signals into electrical signals.
️· It's available in two variants:
- Short/Intermediate Reach: Uses a PIN photodiode.
- Long Reach: Uses an avalanche photodiode (APD).
️· It features a Signal Detect circuit that provides a logic low output when the incoming optical signal is insufficient.

2. Key Specifications

️· Data Rate: 2.48832 Gbps (OC-48/STM-16)
️· Wavelength Range: 1100 nm to 1600 nm
️· Operating Temperature: -40°C to 85°C (specific part dependent on ordering)
️· Supply Voltage: 5.0V (typical)
️· Output Voltage Swing: 0.4V to 0.95V (typical)
️· Jitter Tolerance: Complies with ITU-T G.958.
️· Signal Detect Hysteresis: 0.5 to 1.0 dB

3. Features & Functions

️· Photocurrent Monitoring: The photocurrent can be monitored via a voltage drop across an external resistor connected to the PM pin.
️· APD Bias Voltage: The APD Bias Voltage is temperature compensated.
️· Differential Outputs: DATA and CLOCK outputs are differential and need to be AC-coupled into a 50-ohm load.
️· Signal Detect Output: Provides a logic low signal if optical signal is too weak.

4. Ordering Information & Options

️· Ordering codes include options for:
- Reach (Short/Intermediate/Long)
- Pigtail type (FC, ST, SC)
- Operating temperature range
