The 64B/66B modes do not use the SYNC signal for initialization, however it may be used for NCO synchronization. When toggled low in 8B/10B modes this input initiates code group synchronization (see the Code Group Synchronization (CGS) section). After code group synchronization, this input must be toggled high to start the initial lane alignment sequence (see the Initial Lane Alignment Sequence (ILAS) section). A differential SYNC signal can be used instead by setting SYNC_SEL to 1 and using TMSTP± as a differential SYNC input. Tie this pin to GND if differential SYNC (TMSTP±) is used as the JESD204C SYNC signal.
SYSREF+K1IThe SYSREF positive input is used to achieve synchronization and deterministic latency across the JESD204C interface. This differential input (SYSREF+ to SYSREF–) has an internal untrimmed 100-Ω differential termination and can be AC-coupled when SYSREF_LVPECL_EN is set to 0. This input is self-biased when SYSREF_LVPECL_EN is set to 0. The termination changes to 50 Ω to ground on each input pin (SYSREF+ and SYSREF–) and can be DC-coupled when SYSREF_LVPECL_EN is set to 1. This input is not self-biased when SYSREF_LVPECL_EN is set to 1 and must be biased externally to the input common-mode voltage range provided in the Recommended Operating Conditions table.
SYSREF–L1ISYSREF negative input
TDIODE+K2ITemperature diode positive (anode) connection. An external temperature sensor can be connected to TDIODE+ and TDIODE– to monitor the junction temperature of the device. This pin can be left disconnected if not used.
TDIODE–K3ITemperature diode negative (cathode) connection. This pin can be left disconnected if not used.
TMSTP+B1ITimestamp input positive connection or differential JESD204C SYNC positive connection. This input is a timestamp input, used to mark a specific sample, when TIMESTAMP_EN is set to 1. This differential input is used as the JESD204C SYNC signal input when SYNC_SEL is set 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 a JESD204C SYNC. 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- and DC-coupled configurations. The common-mode voltage must be within the range provided in the Recommended Operating Conditions table when both AC and DC coupled. This pin can be left disconnected and disabled (TMSTP_RECV_EN = 0) if SYNCSE is used for JESD204C SYNC and timestamp is not required.
TMSTP–C1ITimestamp input positive connection or differential JESD204C SYNC negative connection. This pin can be left disconnected and disabled (TMSTP_RECV_EN = 0) if SYNCSE is used for JESD204C SYNC and timestamp is not required.
