AMX 270
Active
Mux
The GuideTech AMX 270 is an active front-end extension
of GuideTech’s Femto family of Continuous Time
Interval Analyzer (CTIA) systems. The combination of
the AMX 270 and the Femto greatly improves and expands
precision timing measurement capability on any test platform.
|
Programmable SE/DF
channels provide application flexibility with a
single universal system configuration and improve
measurement accuracy by minimizing switching on
the ATE loadboard.
The AMX 270 "CTIA” architecture improves
accuracy by bringing 32 channels of critical
front-end input circuitry of GuideTech’s
Femto Continuous Time Interval Analyzer (CTIA)
systems up close to the device under test. |
16 to 32 Channels of Precision Timing Measurement
The fast ECL multiplexer of the AMX 270 expands the
input capacity of Femto timing measurement systems to
up to 32 channels while still maintaining the Femto’s
high throughput for cost-sensitive test applications.
SE/DF Measurement Flexibility & Simple Loadboards
The AMX 270 supports any combination of single-ended
(SE) and differential (DF) measurements with a single
system configuration. The universal flexibility of the
AMX 270 is achieved by innovative input circuit design
that allows users to programmably switch between SE and
DF measurements with programmable input termination at
run-time. These 32 fully-flexible SE/DF channels simplify
loadboard layout and also minimize switching-related
signal degradation due to loadboard impedance mismatching.
Precise Timing Measurements on Any ATE System
The “distributed CTIA” architecture of the
AMX 270 separates the critical front-end input circuits
from the Femto CTIA system, bringing them up to the ATE
testhead, close to the device under test. The 2.7GHz
analog input bandwidth of the AMX 270 coupled with short,
high-bandwidth connections to the loadboard minimize
device output loading and ensure the minimum signal degradation
of low-voltage, high-frequency devices.
The Ideal Solution for Any test Application
Timing is everything in semiconductor manufacturing
test. Time-to-Market. Time-to-Volume. Time-to-Profit.
Timing test accuracy. Test time. At GuideTech, we understand
timing. With timing in mind, GuideTech designed the AMX
270 solution for the Femto CTIA systems to enhance precision
timing measurement capability on an increased number
of channels. The AMX 270/Femto solution easily integrates
onto any digital or mixed-signal ATE platform to dramatically
improve measurement accuracy, speed and throughput and
to get you to market/volume/profit on time and within
budget.
