Deglitcher
A deglitching circuit has been added to the Chip Select
input of the LTC1289 to minimize the effects of errors
caused by noise on that input. This circuit ignores changes
in state on the CS input that are shorter in duration than
one ACLK cycle. After a change of state on the CS input, the
LTC1289 waits for two falling edge of the ACLK before
recognizing a valid chip select. One indication of CS
recognition is the DOUT line becoming active (leaving the
Hi-Z state). Note that the deglitching applies to both the
rising and falling CS edges.
CS Low During Conversion
In the normal mode of operation, CS is brought high
during the conversion time. The serial port ignores any
SCLK activity while CS is high. The LTC1289 will also
operate with CS low during the conversion. In this mode,
SCLK must remain low during the conversion as shown in
the following figure. After the conversion is complete, the
DOUT line will become active with the first output bit. Then
the data transfer can begin as normal.
