The TPS7A4501-SP is a low-dropout (LDO) regulator optimized for fast-transient response. The 5962-1222402VHA can supply 750 mA of output current with a dropout voltage of 300 mV. The 5962R1222403VXC can supply 1.5 A of output current with a dropout voltage of 320 mV. Quiescent current is well controlled; it does not rise in dropout, as with many other regulators. In addition to fast transient response, the TPS7A4501-SP regulator has very-low output noise, which makes it ideal for sensitive RF supply applications.

Output voltage range is from 1.21 to 20 V. The TPS7A4501-SP is stable with output capacitance as low as 10 µF. Small ceramic capacitors can be used without the necessary addition of ESR, as is common with other regulators. Internal protection circuitry includes reverse-battery protection, current limiting, thermal limiting, and reverse-current protection. The device is available as an adjustable device with a 1.21-V reference voltage. The 5962-1222402VHA is available in 10-pin CFP (U) package and 5962R1222403VXC is available in thermally-enhanced 10-pin CFP (HKU) package. Known good die (KGD) option is available for both 5962-1222402V9A for non-RHA version and 5962R1222403V9A for RHA.

TIDA-010191 — 航太級多通道 JESD204B 15-GHz 時脈參考設計

相位陣列天線和數位波束成形技術，是提高未來航太雷達成像和寬頻衛星通訊系統的性能的關鍵技術。數位波束成形與類比波束成形不同，通常每個天線元件需要一套資料轉換器。這些轉換器需要具有具體定義相位關係的時鐘。此參考設計展示如何透過已定義及可調整相位關係，產生低雜訊 MHz 至 GHz 時脈訊號。在發生單一事件後，甚至可能恢復時脈階段。透過操作兩個 ADC12DJ3200QML-SP 評估模組，及在 3.2 GHz 時其對應之 FPGA 架構擷取平台，以及 10-ps 板對板偏斜的情況，藉此來展示 JESD204B 支援。
