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 100Ω differential termination and can be AC-coupled when TMSTP_LVPECL_EN is set to 0. The termination changes to 50Ω 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. |
