Q	What are the applications that the PTN3700 is most suitable for?
A	The PTN3700 is most suitable for multimedia smart phone applications. In particular, it is most relevant when there is a hinged video display. Other applications that it is suitable for include handheld and portable devices such as video players and consumer devices such as camcorder and printers with an LCD display.

Q	Can the PTN3700 support bi-directional half-duplex operation?
A	The PTN3700 cannot support bi-directional half-duplex operation. Please contact Interface.Support@NXP.com for discussions on our future roadmap.

Q	Is anything special needed for the transmission medium?
A	No. The PTN3700 can be used with typical differential transmission medium such as flex circuits, printed circuit boards, or cables.

Q

How long is the link length that PTN3700 is able to support?

A

This significantly depends on the properties of the link medium (including connectors, launches, and PCB) such as loss per unit length over frequency, noise susceptibility of the medium, as well as the degree to which skew between data and clock lanes can be managed. Frequency of operation is also a factor. However, the PTN3700 has been proven to effectively drive up to 25cm of typical flex foil cable in laboratory evaluations. For specific use cases that require lengthy serial interconnect, please contact Interface.Support@NXP.com.

Q	Are there any printed circuit board guidelines available?
A	Yes. Please refer to Section 12 of the PTN3700 datasheet.

Q	Are example schematics using the PTN3700 available for reference purposes?
A	Yes. Please contact Interface.Support@NXP.com.

Q	What circuit simulation models are available for the PTN3700?
A	A full IBIS model is available for circuit simulation. Please visit our PTN circuit simulation models page or contact Interface.Support@NXP.com.
