TLK1501: TLK1501 to SFF Transceiver Transmission Line

user795775

Part Number: TLK1501

Hello.
Connect TLK1501 and SFF transceiver.
SFF transceiver
The impedance of TX and RX is 100Ω differential.
Impedance control of TLK1501 and SFF transceiver is 100Ω differential.
Is there not a problem?
Thank you.

Hi,

According to the datasheet, the primary application of TLK1501 is transmission of 50 ohm controlled impedance media. RX and TX signal transmission lines should be impedance matched to 50 ohms.

Best,

Lucas

Thank you for your response.
I have one more question.
How can I connect the RX/TX (CML) of TLK1501 to the LVDS interface?
Thank you.

Hi,

Can you clarify, what LVDS interface are you referring to? Are you asking how to connect the DINRX and DOUTTX pins to your SFF transceiver so the TLK1501 can receive and transmit high-speed data? It would be helpful if you can share a block diagram of your system so I can better understand how you are using the TLK1501.

Best,

Lucas
