Figure 22. Secondary Communication Data Format—Write Cycle
Figure 23. Clock Generation Subsystem
The architecture of the dual PLL scheme allows for fast
lock time on initial start-up, fast lock time when
changing modem sample rates, high noise immunity,
and the ability to change modem sample rates with a
single register write. A large number of MCLK
frequencies between 1 MHz and 60 MHz are supported.
MCLK should be from a clean source, preferably
directly from a crystal with a constant frequency and no
dropped pulses.
In serial mode 2, the Si3021 operates as a slave device.
The clock generator is configured (by default) to set the
SCLK output equal to the MCLK input. The net effect is
the clock generator multiplies the MCLK input by 20. For
further details of slave mode operation, refer to "Multiple
Device Support" on page 25.
Programming the Clock Generator
As noted in Figure 23, the clock generator must output a
clock equal to 1024
"
Fs, where Fs is the desired
sample rate. The 1024
"
Fs clock is determined through
programming of the following registers:
Register 7—N1 divider, 8 bits.
Register 8—M1 divider, 8 bits.
Register 9—N2/M2 dividers, 4 bits/4 bits.
Register 10—CGM, 1 bit.
When using the Si3035 for modem applications, the
clock generator can be programmed to allow for a single
register write to change the modem sampling rate.
These standard sample rates are shown in Table 17.
The programming method is described below.
