Application Circuits
The application circuits in this chapter show the various communication possibilities of the TLI5012B E1000. The
pin output mode configuration is device-specific and it can be either push-pull or open-drain. The bit IFAB_OD
(register IFAB, 0D_H) indicates the output mode for the IFA, IFB and IFC pins. The SSC pins are by default push-
pull (bit SSC_OD, register MOD_3, 09_H).
Figure 3-1 shows a basic block diagram of a TLI5012B E1000 with Incremental Interface and SSC configuration.
The derivate TLI5012B E1000 is by default configured with push-pull IFA (IIF_A), IFB (IIF_ B) and IFC (IIF_IDX)
pins.

In case that the IFA, IFB and IFC pins are configurated via the SSC interface as open-drain pins, three resistors
(one for each line) between output line and V_DD would be recommended (e.g. 2.2kΩ).
