-====== EVALUATING THE ADAR1000-EVAL1Z (STINGRAY) ANALOG BEAMFORMING FRONT-END ======
+====== ADAR1000EVAL1Z (STINGRAY) ANALOG BEAMFORMING FRONT-END ======
-====== (UNDER CONSTRUCTION) ======
 ====== GENERAL DESCRIPTION ======
 The ADAR1000-EVAL1Z evaluation board is an analog beamforming front-end designed for testing the performance of the [[adi>adar1000|ADAR1000]] and [[adi>adtr1107|ADTR1107]]. The [[adi>adar1000|ADAR1000]] is an 8 GHz to 16 GHz, 4-Channel, X Band and Ku Band Beamformer IC. The [[adi>adtr1107|ADTR1107]] is a 6 GHz to 18 GHz, Front-End Transmit/Receive module.
-The ADAR1000-EVAL1Z board consists of 8 RF cells. Each cell contains a core [[adi>adar1000|ADAR1000]] surrounded by four [[adi>adtr1107|ADAR1107s]]. All RF input/outputs on the evaluation board are brought out to SMPM coaxial connectors. There is a 12V power input and all required voltage rails for the board are generated on-board. Digital control of the board as well as the beamformers is enabled using either an [[adi>SDP-S|System Demonstration Platform (SDP-S)]] connector or a dual PMOD interface. Control signals for the board are expected to be 3.3V logic with on-board level translators converting this to the on-chip logic level of 1.8V.

 ===== Board Power Control =====
-The ADAR1000-EVAL1Z board's power tree is controlled using two signals, **PWR_UP_DOWN** and **+5V_CTRL**. Due to the default settings of the [[adi>adar1000|ADAR1000]] on powerup, the [[adi>adar1107|ADAR1107]] PAs need to be protected so as not to be destroyed when power is applied. The easiest way to control this is to power everything on the board except for the [[adi>adar1107|ADAR1107s']] +5V rail, initialize the [[adi>adar1000|ADAR1000s]] to put the [[adi>adar1107|ADAR1107]] PAs into a safe state, and then power up the +5V rail.

 Both **PWR_UP_DOWN** and **+5V_CTRL** are controlled with pulses, not logic levels, as they are inputs to flip-flops rather than enable signals directly.
 ==== Powerup Procedure ====
-  - Apply +12V to either P1 or P2. Note the red LED (D3) on the bottom of the board. When lit, 12V is applied and the hot swap circuit is active. At this point, no RF rails are powered, but some miscellaneous rails are up:

     * +1.8V_INT (U9, [[adi>adp150|ADP150]])
     * -6.0V_INT (U10, [[adi>ADP5074|ADP5074]])
-  - Pulse the **PWR_UP_DOWN** signal to sequence the first RF power rails. Once the power sequencer is finished, the ADAR1000s are fully powered up and the ADTR1107s are partially powered. This is indicated with an orange LED (D6).
