Hi All,

I am looking for different topologies integrating a differential interface with the following requirements:

- differential interface with on-chip 50 Ohm termination  
- very small power consumption
- the differential signal provides is switched current source with 5mA. both input lines are externally terminated with 50 Ohms to 3.3V.
- the input frequency is 400 MHz

What kind of topology would be the best as the complete system is very jitter sensitive ?  

Thanx for the hopefully incomming answers,

Linus
