General Description
HTF’ HTST-ERTx/HTST-ERTx-2/HTST-ERTx-3/HTST-ERTx-4/ HTST-ERTx-6 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.
The HTST-ERTx/ HTST-ERTx-3 are compatible with 1000BASE-X auto-negotiation and support a SERDES, but do not have a link indication feature.
The HTST-ERTx-2 is compatible with 1000BASE-X auto-negotiation, but does not have a link indication feature (RX_LOS is internally grounded).
The HTST-ERTx-4/ HTST-ERTx-6 are compatible with 1000BASE-X auto-negotiation, and have a link indication feature. PHY is disabled when TX_ disable is high or open.
Low-Speed Signals Electronic Characteristics
MOD_DEF (1) (SCL) and MOD_DEF (2) (SDA) are open drain CMOS signals. Both MOD_ DEF (1) and MOD_DEF (2) must be pulled up to host_ VCC.
Parameter | Symbol | Min. | Typical | Max | Unit | Notes |
SFP Output LOW | VOL | 0 | 0.5 | V | 4.7k to 10k pull-up to host_ Vcc. | |
SFP Output HIGH | VOH | host_ Vcc -0.5 | host_ Vcc +0.3 | V | 4.7k to 10k pull-up to host_ Vcc. | |
SFP Input LOW | VIL | 0 | 0.8 | V | 4.7k to 10k pull-up to Vcc. | |
SFP Input HIGH | VIH | 2 | Vcc + 0.3 | V | 4.7k to 10k pull-up to Vcc. |
General Specifications
Parameter | Symbol | Min. | Typical | Max | Unit | Notes |
Data Rate | BR | 10 | 1000 | Mb/s | IEEE 802.3 compatible | |
Cable Length | L | 100 | m | Category 5 UTP. BER <10-12 |
Notes:
1. Clock tolerance is +/- 50 ppm
2. By default, the HTST-ERTx is a full duplex device in preferred master mode
3. Automatic crossover detection is enabled. External crossover cable is not required
4. By default, 1000 BASE-T operation requires the host system to have an SERDES interface with no clocks.
FAQ
1、Question: "This is 1000m sfp-t transceiver, not 10/100/1000m multi-rate sfp-t." does this only work at gigabit? Does it not work at 100baset at all?
Answer: Yes, it only works at gigabit.
2、Question: Will this work with the Juniper?
Answer: Yes, it will.
3、Question: Will this work with Cisco?
Answer: Yes, it will.
