This pin should be tied to GND if differential SYNC (TMSTP±) is used as the JESD204B SYNC signal.
SYSREF+ L1 I SYSREF positive input used to achieve synchronization and deterministic latency across the JESD204B interface. This differential input (SYSREF+ to SYSREF–) has an internal 100-Ω differential termination. It is self-biased when AC coupled (SYSREF_LVPECL_EN must be set to 0), but can be DC coupled by setting SYSREF_LVPECL_EN to 1, which changes the internal termination to 50-Ω single-ended termination to ground on each SYSREF+ and SYSREF- input. The common mode voltage must be within the recommended range when DC coupled.

This input is used as the JESD204B SYNC signal when SYNC_SEL is set to use TMSTP+ and TMSTP– as the JESD204B SYNC signal. For additional usage information as timestamp input, see the Timestamp section. This pin can be left disconnected if SYNCSE is used and timestamp is not required.
