The LMK04832-SP is a high performance clock conditioner with JEDEC JESD204B support for space applications.

The 14 clock outputs from PLL2 can be configured to drive seven JESD204B converters or other logic devices using device and SYSREF clocks. SYSREF can be provided using both DC and AC coupling. Not limited to JESD204B applications, each of the 14 outputs can be individually configured as high-performance outputs for traditional clocking systems.

The LMK04832-SP can be configured for operation in dual PLL, single PLL, or clock distribution modes with or without SYSREF generation or reclocking. PLL2 may operate with either internal or external VCO.

The high performance combined with features like the ability to trade off between power and performance, dual VCOs, dynamic digital delay, and holdover allows the LMK04832-SP to provide flexible high performance clocking trees.

The LMK04832-SP comes in a 10.9-mm × 10.9-mm, 64-pin CFP package.

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。
