Because the anti-aliasing and smoothing filters track the Sample Rate Select bits, one must, for
optimum performance, maintain the external clock at one of the four possible frequencies shown in the
table for
Analog Structure (Right Half)
description on page 36 AND set the Sample Rate Configuration
bits to one of the four values in order to properly set the filters to their correct cutoff frequency as
described in
Analog Structure (Right Half)
description on page 36. The duty cycle on the input clock is
not critical when CKD2 is set to ONE, as the clock is immediately divided by two (internally). If the
MCLK is not used, this input should be connected to V
SSD
.
A0, A1 (Address Pins)
These two pins are normally strapped for the desired address that the Winbond I5216 will have on the
I
2
C serial interface. If there are four of these devices on the bus, then each must be strapped
differently in order to allow the master device to address them individually. The possible addresses
range from 80h to 87h, depending upon whether the device is being written to, or read from, by the
host.
The Winbond I5216 has a 7-bit slave address of which only A0 and A1 are pin programmable. The
eighth bit (LSB) is the R/W bit. Thus, the address will be 1000 0xy0 or 1000 0xy1
