10/100/1000M Copper SFP w/ Link Indicator

ASCENT’S SFP-AG-CO-04 10/100/1000 BASE-T Copper Small Form Pluggable (SFP) transceivers are based on the SFP Multi Source Agreement (MSA) . They are compatible with the Gigabit Ethernet standards as specified in IEEE Std 802.3. The 10/100/1000 BASE-T physical layer IC (PHY) can be accessed via I2C, allowing access to all PHY settings and features.

•    Up to 1.25 Gb/s bi-directional data links

•    Hot-pluggable SFP footprint

•    Low power dissipation(1.05W typical)

•    Compact RJ-45 connector assembly

•    Fully metal enclosure, for lower EMI

•    RoHS compliant and lead-free

•    Single +3.3V power supply

•    10/100/1000 BASE-T operation in host systems with SGMII interface

•    1.25 Gigabit Ethernet over Cat 5 cable


3.3V Volt Electrical Power Interface

The SFP‑AG‑CO‑04 has an input voltage range of 3.3 V ± 5%. The 4V maximum voltage is not allowed for continuous operation.

Notes:

1. Clock tolerance is ± 50 ppm

2. By default, the SFP‑AG‑CO‑04 is a full duplex device in preferred master mode

3. Automatic crossover detection is enabled. External crossover cable is not required

4. 10/100/1000 BASE‑T operation requires the host system to have an SGMII interface with no clocks.
