NAME J8 ORB1 O Fast overrange detection status for channel B for the OVR_T1 threshold. When the analog input exceeds the threshold programmed into OVR_T1, 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. J9, J10 DGND — Digital supply ground. Tie AGND and DGND to a common ground plane (GND) on the circuit board. J11 DB5– O High-speed serialized data output for channel B, lane 5, negative connection. This pin can be left disconnected if not used. For information regarding reliable serializer operation, see footnote (1) in the Pin Functions table. J12 DB1– O High-speed serialized data output for channel B, lane 1, negative connection. This pin can be left disconnected if not used. For information regarding reliable serializer operation, see footnote (1) in the Pin Functions table. K1 SYSREF+ I The SYSREF positive input is used to achieve synchronization and deterministic latency across the JESD204B 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. K2 TDIODE+ I Temperature 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. K3 TDIODE– I Temperature diode negative (cathode) connection. This pin can be left disconnected if not used. K4 VA19 I 1.9-V analog supply K5 VA11 I 1.1-V analog supply K6 PD I This pin disables all analog circuits and serializer outputs when set high for temperature diode calibration only. Do not use this pin to power down the device for power savings. Tie this pin to GND during normal operation. For information regarding reliable serializer operation, see footnote (1) in the Pin Functions table. K7 NCOB0 I LSB of NCO selection control for DDC B. NCOB0 and NCOB1 select which NCO, of a possible four NCOs, is used for digital mixing when using a complex output JMODE. The remaining unselected NCOs continue to run to maintain phase coherency and can be swapped in by changing the values of NCOB0 and NCOB1 (when CMODE = 1). This pin is an asynchronous input. See the NCO Fast Frequency Hopping (FFH) and NCO Selection sections for more information. Tie this pin to GND if not used. K8 ORB0 O Fast overrange detection status for channel B for the OVR_T0 threshold. When the analog input exceeds the threshold programmed into OVR_T0, 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. K9, K10 VD11 I 1.1-V digital supply K11 DB5+ O High-speed serialized data output for channel B, lane 5, positive connection. This differential output must be AC-coupled and must always be terminated with a 100-Ω differential termination at the receiver. This pin can be left disconnected if not used. For information regarding reliable serializer operation, see footnote (1) in the Pin Functions table. K12 DB1+ O High-speed serialized data output for channel B, lane 1, positive connection. This differential output must be AC-coupled and must always be terminated with a 100-Ω differential termination at the receiver. This pin can be left disconnected if not used. For information regarding reliable serializer operation, see footnote (1) in the Pin Functions table. L1 SYSREF– I SYSREF negative input L2, L3, L4, L5, L6, L7 AGND — Analog supply ground. Tie AGND and DGND to a common ground plane (GND) on the circuit board. L8 DB7+ O High-speed serialized data output for channel B, lane 7, positive connection. This differential output must be AC-coupled and must always be terminated with a 100-Ω differential termination at the receiver. This pin can be left disconnected if not used. For information regarding reliable serializer operation, see footnote (1) in the Pin Functions table. L9 DB7– O High-speed serialized data output for channel B, lane 7, negative connection. This pin can be left disconnected if not used. For information regarding reliable serializer operation, see footnote (1) in the Pin Functions table. |
