1000BASE-SX SFP Transceiver Module Cisco GLC-SX-MM Compatible 850nm 550m LC
Absolute Maximum Ratings
| Parameter | Symbol | Min. | Max. | Unit | Note |
| Supply Voltage | Vcc | -0.5 | 4.0 | V | |
| Storage Temperature | TS | -40 | 85 | °C | |
| Relative Humidity | RH | 0 | 85 | % | |
Note: Stress in excess of the maximum absolute ratings can cause permanent damage to the transceiver.

| Transmitter |
| Differential data input swing | VIN,PP | 250 | | 1200 | mVpp | 1 |
| Tx Disable Input-High | VIH | 2.0 | | Vcc+0.3 | V | |
| Tx Disable Input-Low | VIL | 0 | | 0.8 | V | |
| Tx Fault Output-High | VOH | 2.0 | | Vcc+0.3 | V | 2 |
| Tx Fault Output-Low | VOL | 0 | | 0.8 | V | 2 |
| Input differential impedance | Rin | | 100 | | Ω | |
| Receiver |
| Differential data output swing | Vout,pp | 250 | | 550 | mVpp | 3 |
| Rx LOS Output-High | VROH | 2.0 | | Vcc+0.3 | V | 2 |
| Rx LOS Output-Low | VROL | 0 | | 0.8 | V | 2 |
Notes:
1. TD+/- are internally AC coupled with 100Ω differential termination inside the module.
2. Tx Fault and Rx LOS are open collector outputs, which should be pulled up with 4.7k to 10kΩ resistors on the host board. Pull up voltage between 2.0V and Vcc+0.3V.
3. RD+/- outputs are internally AC coupled, and should be terminated with 100Ω (differential) at the user SERDES.
Applications
