DETAILED INFORMATION
The TSA1001 is a High Speed analog to digital
converter based on a pipeline architecture and the
latest deep submicron CMOS process to achieve
the best performances in terms of linearity and
power consumption.
The pipeline structure consists of 9 internal con-
version stages in which the analog signal is fed
and sequentially converted into digital data.
Each 8 first stages consists of an Analog to Digital
converter, a Digital to Analog converter, a Sample
and Hold and a gain of 2 amplifier. A 1.5bit conver-
sion resolution is achieved in each stage. The lat-
est stage simply is a comparator. Each resulting
LSB-MSB couple is then time shifted to recover
from the conversion delay. Digital data correction
completes the processing by recovering from the
redundancy of the (LSB-MSB) couple for each
stage. The corrected data are outputted through
the digital buffers.
Signal input is sampled on the rising edge of the
clock while digital outputs are delivered on the fall-
ing edge of the Data Ready signal.
The advantages of such a converter reside in the
combination of pipeline architecture and the most
advanced technologies. The highest dynamic per-
formances are achieved while consumption re-
mains at the lowest level.
Some functionalities have been added in order to
simplify as much as possible the application
board. These operational modes are described in
the following table.
The TSA1001 is pin to pin compatible with the
8bits/40Msps
TSA0801,
the
10bits/50Msps
TSA1002 and the 12bits/50Msps TSA1201. This
ensures a conformity within the product family and
above all, an easy upgrade of the application.
OPERATIONAL MODES DESCRIPTION
Data Format Select (DFSB)
When set to low level (VIL), the digital input DFSB
provides a twoís complement digital output MSB.
This can be of interest when performing some fur-
ther signal processing.
When set to high level (VIH), DFSB provides a
standard binary output coding.
Output Enable (OEB)
When set to low level (VIL), all digital outputs re-
main active and are in low impedance state. When
set to high level (VIH), all digital outputs buffers
are in high impedance state. This results in lower
consumption while the converter goes on sam-
pling.
When OEB is set to low level again, the data is
then valid on the output with a very short Ton de-
lay.
