D.2 Bit Rate Generator
note that the BRGs will only generate these standard bit
rates if the Oscillator Circuit is running at 3.6864 MHz (for
the bit rates presented in Table 15) or running at 7.3728
MHz (for the bit rates presented in Table 15A). The actual
Figure 31. Block Diagram of the Bit Rate Generator portion of the Timing Control Block, for
Channels A and B
Please
clock frequencies output from the BRGs are at 16 times
these rates.
