Recommended Parts for Analog SocketModems
Disclaimer:
Multi-Tech Systems makes no warranty claims for vendor product recommendations listed below. Other
vendor products may or may not operate satisfactorily. Multi-Tech System’s recommended vendor products
only indicate that the product has been tested in controlled conditions and was found to perform
satisfactorily.
Notes:
These parts are RoHS compliant.
Use surface mount ferrites on Tip and Ring (T&R) to mitigate emission levels out the RJ-11 cable. 220pF
capacitors are also used on T&R to reduce the common mode emissions that may be present in certain
systems. See the Tip and Ring drawings in each analog SocketModem chapter.
The ferrite and capacitors also aid in reducing the effects of transients that may be present on the line.
