Other Parts Discussed in Thread: TLK1221

For the TLK1221 ETHERNET TRANSCEIVER, what is the LVTTL output impedance for the RD[9:0], RBC[1:0] and SYNC/PASS outputs?

Lee,

I have moved your post to the High Speed Interface forum so that it is seen by the experts for that device.

Hi Lee,

Output impedande value is not specified in datasheet but it should be in the 30 - 50 Ohm range. Even datasheet mentions:

"The primary application of these devices is to provide building blocks for point-to-point" baseband data transmission over controlled-impedance media of 50 Ohms"
