Low Speed Single Terminal Signal and I2C Interface of Optical Module

user503335153

Other Parts Discussed in Thread: FPC402, FPC401

Please help me recommend an I2C interface for optical modules, an I2C interface for converting one I2C into multiple optical modules, and a dedicated IO for optical modules, which is usually used in cases where IO and I2C are not enough.

Hello,

What are you looking for regarding an I2C device? Do you need voltage translation (and if so, what supply voltages are used)? Do you know if you need a buffer (i.e., in order to help drive larger parasitic capacitance? What do you mean by a dedicated IO?

Regards,
Max

Without buffer and level conversion, IO expansion and I2C expansion are implemented simultaneously. IO can be a general purpose IO. This chip is generally used on optical modules. I can't find it on the official website. There are I2C extension chips and IO extension chips on the official website, but there are not both.

I have found Fcp401、FCP402, but the official website has no information. Can you provide the following datasheet? sparkmma@163.com。

Hello,

Are you sure that is a TI device? I'm not able to find any information on it. Can you show me where you found this device?
