| The
DEVA018 single axis sine-wave interpolator can accept
11µA or 1vpp differential sine / cosine signals and
produce RS422 differential square wave quadrature signals.
The interpolation factor may be set to 1, 2, 5 or 10 times
e.g. provides 0.5u resolution from a 20u pitch scale. For
1vpp the inputs may be terminated with on-board 120ohm resistors.
The maximum input rate is 250kHz. The maximum output count
rate is 10MHz.
The DEVA018 operates from +5v which
may be supplied either from the input or output connector.
The output connector is pin to pin compatible
with all Deva's encoder interface and motion control
products. All unused pins are passed through from input to
output.
The following variant of the interpolator
is available on request.
The Deva 018-1SIN-MIT1 accepts 2vpp single ended signals
biased on 2.5v. The 2.5v bias must available from the encoder
to connect to the inverting input.
The Deva 018-1SIN-MIT1 is known to
be compatible with the Mitutoyo AT102, AT111, AT112, AT115
and AT181 scales, along with others of the same output format.
