TMS320C6746: Difference between buffered serial and serial port in TMS320VC549 OR TMS320C50

Hello Sowmiya annamalai

Thank you for the query. 

It would help if you could point to the section in the datasheet or the TRM that you are referencing. 

Since the question is generic, please refer below inputs. If you need additional information, please refer to the TRM.

The multichannel buffered serial port (McBSP) allows direct interface to other TI DSPs, codecs, and other devices in a system. The primary use for the McBSP is for audio interface purposes. The primary audio modes that are supported are the AC97 and IIS modes. In addition to the primary audio modes, the McBSP can be programmed to support other serial formats but is not intended to be used as a high-speed interface. The McBSP consists of a data path and a control path that connect to external devices. Separate pins for transmission and reception communicate data to these external devices. The CPU communicates to the McBSP using 32-bit-wide control registers accessible via the internal peripheral bus.

A serial port could be an UART used for asynchronous communication.

Hello Sowmiya annamalai

Please refer below inputs

The McBSP is a highly programmable serial interface that can support connections to many different devices.  The signals and programming of the interface are described in the Multichannel Buffered Serial Port (McBSP) User's Guide for KeyStone Devices which is available on the C6657 or other devices on the webpage.

Thank you for the inputs.

Also, Is it possible to operate MCBSP in two different frequencies (for transmit one clock and receive one clock frequency)?

We recommend discussing one topic in a thread to be able to scale with other E2E users. The thread topic is expected to match with the heading for searchability.

if you have queries on the MCBSP capabilities, please start a new thread with title MCBSP interface and add your queries.

Also be sure to mention the device you have in mind rather that having multiple devices since the capabilities change with devices.
