TPS92661-Q1: MCU CLK

Hello,

According to an expert on the device:

"Per spc. Page 33 tps92661-q1

Baud rate:

The baud rate is based on the CLOCK input and is one-sixteenth of the CLOCK input frequency (see Table 1 for

some examples). The UART uses 16× oversampling on the incoming asynchronous RX signal.

Example:

8 MHz = 500kbps Baud Rate

CLK:

7.4.1.2 Clock (CLK Pin)

The CLK pin is the input for the primary system clock. It serves as the time basis for both the UART, as well as

the LED PWM hardware. The device functions with a clock input as high as 16 MHz. The clock rate should be

selected based on the desired UART bit rate. CLOCK can be provided by the PWM peripheral of the master

microcontroller, or by a local oscillator. All TPS92661s on the same network should share the same clock."
