Application Information

The TPMC151 is a standard single-width 32-bit PMC

module and supports a 33 MHz / 32-bit universal (5 V /

3.3 V) PCI interface.

The TPMC151-10R provides 4 channels of Resolver or

LVDT/RVDT to Digital Converter with 16-bit resolution. It

accepts inputs signals up to 12 VRMS, with frequencies

ranging from 1 kHz to 20 kHz and allows tracking rates up

to ¼ of th e e xc ita tio n fre q u e n c y (i.e . 1 0 k H z -> 2 5 0 0 rp s ).

The converter provides a digital angle, respectively stroke

value, and a digital velocity value. For LVDT/RVDT differential

and ratiometric sensor configuration is supported.

The TPMC151 provides individual excitation outputs with

software selectable excitation frequency and output voltage

swing for each channel. Adjustable frequency is ranging

from 1 kHz to 20 kHz and the output voltage range is 0 to

12 VRMS with up to 100 mA. No external power supply is

required. Alternatively, an external excitation can be used.

The TPMC151-20R replaces two resolver channels with

two Synchro-to-Digital Converter channels. For Synchro

channels the excitation output is not available and an

external excitation must be used. Synchro channels accept

input signals up to 28 VRMS, with frequencies ranging from

400 Hz to 20 kHz.

All TPMC151 signals are accessible through a 50-pin MDR

type front I/O connector.

Software Support (TPMC151-SW-xx) for different operating

systems is available.
