Digital Filter
The CS5525/26 have eight different linear phase
digital filters which set the output word rates
(OWRs) as stated in Table 2. These rates assume
that XIN is 32.768 kHz. Each of the filters has a
magnitude response similar to that shown in Figure
19. The filters are optimized to settle to full accura-
cy every conversion and yield better than 80 dB re-
jection for both 50 and 60 Hz with output word
rates at or below 15.0 Sps.
The converter’s digital filters scale with XIN. For
example with an output word rate of 15 Hz, the fil-
ter’s corner frequency is typically 12.7 Hz. If XIN
is increased to 64.536 kHz the OWR doubles and
the filter’s corner frequency moves to 25.4 Hz.
Output Coding
The CS5525/26 output data in binary format when
operating in unipolar mode and in two's comple-
ment when operating in bipolar mode.
The output conversion word is 24 bits, or three
bytes long, as shown in Table 5. The MSB is output
first followed by the rest of the data bits in descend-
ing order. For the CS5525 the last byte is composed
of bits D7-D4, which are always logic 1; D3-D2,
which are always logic 0; and bits D1-D0 which are
the two flag bits. For the CS5526 the last byte in-
cludes data bits D7-D4, D3-D2 which are always
logic 0 and the two flag bits.
The OF (Overrange Flag) bit is set to a logic 1 any
time the input signal is: 1) more positive than posi-
tive full scale, 2) more negative than zero (unipolar
mode), 3) more negative than negative full scale
(bipolar mode). It is cleared back to logic 0 when-
ever a conversion word occurs which is not over-
ranged.
The OD (Oscillation Detect) bit is set to a logic 1 any
time that an oscillatory condition is detected in the
modulator. This does not occur under normal operating
conditions, but may occur whenever the input to the
converters is extremely overranged. If the OD bit is set,
