DESCRIPTION
The TSA1041 uses a high density advanced deep
submicron CMOS process, to integrate four High
Speed A/D converters in one circuit. It achieves
simultaneous conversion of four differential inputs
with a resolution of 10 bits at 50MHz maximum
sampling frequency.
The device has an internal PLL to generate 10
times the sampling frequency, used for the
serialization of the 10 bits wide data per channel.
Thus it delivers 40 data on only 8 wires
corresponding to four serialized data LVDS
outputs. The number of pins is limited and the four
ADCs of the TSA1041 fit in a small TQFP48,
reducing board size and simplifying PCB layout.
Moreover the use of LVDS outputs reduces the
noise.
Special
care
is
given
to
minimize
power
consumption at the application by selecting the
proper
consumption
for
a
given
sampling
frequency.
The TSA1041 is available in extended (-40 to
+85°C) temperature range.
APPLICATIONS
s Medical imaging and ultrasound
s Portable instrumentation
s Cable Modem Receivers
s High resolution fax and scanners
s High speed DSP interface
s Particle detector
s High-end cameras
