Description
16
DB4/SCLK
Data Bit 4/Serial Clock. When the device is in its parallel mode, this pin is Data Bit 4, a three-state
TTL-compatible output. When the device is in its serial mode, this becomes the serial clock pin,
SCLK. SCLK is an input and an external serial clock must be provided at this pin to obtain serial
data from the AD7892. Serial data is clocked out from the output shift register on the rising edges
of SCLK after
RFS goes low.
17
DB3/
RFS
Data Bit 3/Receive Frame Synchronization. When the device is in its parallel mode, this pin is Data
Bit 3, a three-state TTL-compatible output. When the device is in its serial mode, this becomes the
receive frame synchronization input with
RFS provided externally to obtain serial data from the
AD7892.
18
DB2
Data Bit 2. Three-state TTL-compatible output. This output should be left unconnected when the
device is in its serial mode.
19
DB1
Data Bit 1. Three-state TTL-compatible output. This output should be left unconnected when the
device is in its serial mode.
20
DB0
Data Bit 0 (LSB). Three-state TTL-compatible output. Output coding is two’s complement for
AD7892-1 and AD7892-3 and straight (natural) binary for AD7892-2. This output should be left
unconnected when the device is in its serial mode.
21
RD
Read. Active low logic input which is used in conjunction with
CS low to enable the data outputs.
22
CS
Chip Select. Active low logic input which is used in conjunction with
RD to enable the data outputs.
23
EOC
End-of-Conversion. Active low logic output indicating converter status. The end of conversion is
signified by a low going pulse on this line. The duration of this
EOC pulse is nominally 100 ns.
24
CONVST
Convert Start. Logic Input. A low-to-high transition on this input puts the track/hold into its hold
mode and starts conversion.
