D9ORBOFast over-range detection status output for channel B. Only used for quad and dual channel devices. Do not connect for single channel device. When the analog input for channel B exceeds the threshold programmed into OVR_T, this status indicator goes high. The minimum pulse duration is set by OVR_N. See the ADC Overrange Detection section for more information. This pin can be left disconnected if not used.
E9ORCOFast over-range detection status output for channel C or additional clock output. The fast over-range detection function is only available for quad channel device. When the analog input for channel C exceeds the threshold programmed into OVR_T, this status indicator goes high. The minimum pulse duration is set by OVR_N. See the ADC Overrange Detection section for more information. This pin can alternatively be used as an additional clock output (DIVREF_C) when enabled by CLKCFG[1:0] or through the SPI register configuration and when PLL_EN is high. When CLKCFG0 and CLKCFG1 are both set low (or disabled through SPI) the ORC output is used to output the over-range signal for ADC channel C.ORC can be programmed as a copy of PLLREFO (CLKCFG[1:0] = 0x1) or as a divide-by-2 (CLKCFG[1:0] = 0x2) or divide-by-4 (CLKCFG[1:0] = 0x3) copy of PLLREFO.

See the ADC Overrange Detection section for more information. This pin can alternatively be used as an additional clock output (DIVREF_D) when enabled by CLKCFG[1:0] or through the SPI register configuration and when PLL_EN is high. When CLKCFG0 and CLKCFG1 are both set low (or disabled through SPI) the ORD output is used to output the over-range signal for ADC channel D.ORD can be programmed as a copy of PLLREFO when any or both of CLKCFG[1:0] are set which will be available at startup if PLL_EN is set high and PD is held low. ORD can be set as a divide-by-2 or divide-by-4 copy of PLLREFO when overridden through the SPI register. A clock out of ORD is only available if a clock is also output from ORC. If only one clock is required then use ORC. This pin can be left disconnected if not used.
M9PDICMOS input to power down the device for power savings or temperature diode calibration. Setting PD high disables PLLREFO and the ORC and ORD clock outputs and therefore this pin should not be used if these clocks are critical for system operation. Tie this pin to GND if not used.
J3, K5PGND—PLL supply ground. Tie AGND, PGND, SE_GND and DGND to a common ground plane (GND) on the circuit board.

Only CLK± can be used for the sampling clock if the PLL is disabled. Tie this pin to GND if the PLL is not used or if CLK± is used as the reference clock input.
K7PLLREFO–ONegative LVDS PLL reference clock output. The clock is repeated from the selected PLL reference clock input (CLK± or SE_CLK). It is available at device power up to clock other devices when PLL_EN is set high and PD is held low. This pin can be left disconnected if not used.

This pin outputs 1.9-V CMOS levels during serial interface read operations. This pin can be left disconnected if not used.
F2SE_CLKISingle-ended PLL reference clock input. This input is selected when PLL_EN is held high and PLLREF_SE is held high. When PLLREF_SE is set low, CLK± is used as the differential PLL reference input. This pin should be tied to GND if not used.
G2SE_GND—Ground reference for single-ended PLL reference clock input. Tie AGND, PGND, SE_GND and DGND to a common ground plane (GND) on the circuit board.
C4SYNCSEISingle-ended JESD204C SYNC signal. This input is an active low input that is used to initialize the JESD204C serial link in 8B/10B modes when SYNC_SEL is set to 0. The 64B/66B modes do not use the SYNC signal. 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). Tie this pin to ground if TMSTP± or JSYNC_N is used as the JESD204C SYNC signal or for 64B/66B encoded JESD204C modes.
K1SYSREF–ISYSREF negative input. Leave this pin disconnected if not used and power down the SYSREF± receiver using SYSREF_RECV_EN.
J1SYSREF+IThe 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. Leave this pin disconnected if not used and power down the SYSREF± receiver using SYSREF_RECV_EN.
K4TDIODE–ITemperature diode negative (cathode) connection. This pin can be left disconnected if not used.
K3TDIODE+ITemperature 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.
D1TMSTP–ITimestamp input negative connection. This pin can be left disconnected and the TMSTP receiver powered down (TMSTP_RECV_EN = 0) if timestamp is not required.
C1TMSTP+ITimestamp input positive connection. This input is a timestamp input, used to mark a specific sample, when TIME_STAMP_EN is set to 1. 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. Can also be used as a differential SYNC input for the JESD204C interface with 8b/10b encoding. This pin can be left disconnected and the TMSTP receiver powered down (TMSTP_RECV_EN = 0) if timestamp is not required.
K9TRIGOUT–ONegative LVDS output for trigger repeated from TMSTP± or clock output generated from the SerDes PLL. This output can be enabled by setting TRIGOUT_EN to 1 and configured by TRIGOUT_MODE. Setting the PD pin high disables this output. This pin can be left disconnected if not used.
J9TRIGOUT+OPositive LVDS output for trigger repeated from TMSTP± or clock output generated from the SerDes PLL. This output can be enabled by setting TRIGOUT_EN to 1 and configured by TRIGOUT_MODE. Setting the PD pin high disables this output. This pin can be left disconnected if not used.
