D1 TMSTP+ I Timestamp input positive connection or differential LVDS SYNC positive connection. This input is used as the timestamp input, used to mark a specific sample, when TIMESTAMP_EN is set 1. This differential input is used as the SYNC signal input when SYNC_SEL is set to 1. This input can be used as both a timestamp and differential SYNC input at the same time, allowing feedback of the SYNC signal using the timestamp mechanism. TMSTP± uses active low signaling when used as the LVDS SYNC signal. For additional usage information, see the Timestamp section.
TMSTP_RECV_EN must be set to 1 to use this input. This differential input (TMSTP+ to TMSTP–) has an internal untrimmed 100-Ω differential termination and can be AC-coupled when TMSTP_LVPECL_EN is set to 0. The termination changes to 50 Ω to ground on each input pin (TMSTP+ and TMSTP–) and can be DC-coupled when TMSTP_LVPECL_EN is set to 1. This pin is not self-biased and therefore must be externally biased for both AC-coupled and DC-coupled configurations. The common-mode voltage must be within the range provided in the Recommended Operating Conditions table when both AC-coupled and DC-coupled. This pin can be left disconnected and disabled (TMSTP_RECV_EN = 0) if SYNCSE is used for the LVDS SYNC signal and timestamp is not required.

E2 SYNCSE I LVDS interface SYNC signal, single-ended active low input used to control sending strobe signals for synchronization or digital interface test patterns. The Digital Interface Test Patterns section describes using the SYNC signal in more detail. The choice of single-ended or differential SYNC (using the TMSTP+ and TMSTP– pins) is selected by programming SYNC_SEL. Tie this pin to ground if differential SYNC (TMSTP±) is used as the SYNC signal.
