16x data rate clock in uart
Hi all,
i have a clock capable of generating freq of 10khz to 16.7khz.I need to get the clock to synchronize with the serial data bits. Following the start bit for a RS232 data frame,Each data bit is sampled at its centre until the stop bit is encountered.
Qn1. Can i use a Digital Phase lock loop to achieve this? what PLL chip is suitable
Qn2.How do i connect up the pins on the PLL chip such that the data and the clock are synchronized together?
see attachment for the desired timing diagram
thanks
