CSI-2 interface - AC specifications

For further information on the subLVDS refer to the specification document: MIPI Alliance

Standard for D_PHY version 0.90.

Note:

When quoting the MIPI specification, the following rules must be followed:

Disclosure of a Specification, or the creation of derivative works of a Specification, may also

be made “as part of STMicroelectronics’s product for the purpose of developing and selling

products complying with the MIPI Specification(s).” MA 3.2(c). In this connection, the MIPI

Board has approved the disclosure only of such portion of the Specification as in the

reasonable judgment of the Member is relevant for the development and/or sale of

Compliant Portions. This may, of course, require the disclosure of the entire Specification

when the situation requires. The Board notes that these provisions of the MA are intended

to assist Members in providing information useful in MIPI compliant product development or

to provide support documentation for the Member's products.

Disclosure is also permitted when, in the opinion of the MIPI Board, such disclosure is a

legitimate derivative use which enables the development or implementation of a MIPI

Specification or development or sale of Compliant Portions. Permission for such disclosures

may be granted by the MIPI Board on a case by case basis and subject to the receipt of a

confidentiality agreement as in the case of a contractor. Examples of such a derived use

may be disclosures to vendors of test equipment or other enabling products. Note: In ALL

permitted cases of disclosure of a MIPI Specification, in whole, or in part, the disclosure

must include (a) the copyright notice contained in the Specification on the first page of the

disclosed portion and on every other page where it appears in the included portions of the

Specification with prominence at least equal to that of the Specification as published by

MIPI. The copyright notice on the first page shall be followed by the following language: “All

rights reserved. This material is reprinted with the permission of the MIPI Alliance, Inc. No

part(s) of this document may be disclosed, reproduced or used for any purpose other than

as needed to support the use of the products of STMicroelectronics”.

UI is equal to 1/(2*fh) where fh is the fundamental frequency of the transmission for a certain bit rate. e.g.

for 600Mbps fh is 300MHz.
