Overview
HD-4702/883 June 1998 CMOS Programmable Bit Rate Generator Description The HD-4702/883 Bit Rate Generator provides the necessary clock signals for digital data transmission systems, such as a UART.
It generates 13 commonly used bit rates using an on-chip crystal oscillator or an external input.
For conventional operation generating 16 output clock pulses per bit period, the input clock frequency must be 2.
4576MHz (i.
e.
, 9600 Baud x 16 x 16, since there is an internal ÷ 16 prescaler).
A lower input frequency will result in a proportionally lower output frequency.
The HD-4702/883 can provide multi-channel operation with a minimum of external logic by having the clock frequency CO and the ÷ 8 ...
