The TIDA-00179 reference design is an EMC compliant universal digital interface to connect to absolute position encoders, like EnDat 2.2, BiSS®, SSI or HIPERFACE DSL®. The design supports a wide input voltage range from 15-60V (24V nom). A connector with 3.3V logic I/O signals allows for direct interface to the host processor like Sitara AM437x or Delfino F28379 to run the corresponding master protocol. Master implementations are available on Sitara AM437x (EnDat2.2, BiSS and HIPERFACE DSL) or Delfino DesignDRIVE (EnDat2.2 and BiSS). The TI design allows the host processor to select between a 4-wire encoder interface like EnDat 2.2 and BiSS or a 2-wire interface with power over RS485 like HIPERFACE DSL. To meet the selected encoder's supply range, the design offers a programmable output voltage with either 5.25V or 11V. This design’s power supply offers protection against over-voltage and short circuit according to the selected encoder’s voltage range to prevent damage during a cable short. TIDA-00179 has been tested up to 100m cable length with EnDat 2.2 and 2-wire HIPERFACE DSL encoders.

The TIDA-00363 TI design provides a solution for EMC-compliant resolver-to-digital converter (RDC) with single-chip PGA411-Q1 with 12-bit angle resolution. PGA411-Q1's integrated boost-converter and exciter amplifier reduces system cost and board space compared to traditional RDC solutions. On-chip protection and diagnostic improve robustness against short-circuit and increase safery by detecting external fault conditions. A high-speed 3.3V SPI interface allows PGA411-Q1 configuration, diagnostics, angle and velocity information.
