Vectron時鐘源和接口電路RTG4耐輻射FPGA的SerDes模塊的時鐘(REFCLK)輸入

This Application Note describes various Vectron clock sources and interface circuits that can be used to drive the Reference Clock (REFCLK) Inputs of the SerDes Blocks of the RTG4 radiation-tolerant FPGA.
The Microchip RTG4 (Radiation-Tolerant Generation4) FPGA (Field Programmable Gate Array) can receive clock signals in two types of clock inputs:
1. Clock signals into the RTG4 general purpose and dedicated clock input pins, for use as a clock to the logic in the Digital Fabric.
2. Clock signals into the SerDes Blocks Reference Clock input pins, which input a reference clock for use by the dedicated high-speed SerDes Blocks on chip.
Of the two types of clock inputs, RTG4 REFCLK Inputs will be examined for this Application Note. The RTG4 REFCLK Inputs can be programmed by a FPGA designer to one of the various receiver types (differential or single-ended signal), and each has logic level requirements that will need direct interface or translation interface circuit connections to work properly when used with a standard clock driver (See Table 3). Information for providing clock input to the RTG4 Digital Fabric (type ‘1’ above) is not presented here, but it can be connected with a standard driver clock the same as providing clock input to the RTG4 REFCLK receivers.
In addition to listing and discussing these devices, this Application Note also summarizes the RTG4 REFCLK Inputs specification logic levels required for the clock source drivers with output logic levels presented in Table 3. The Application Note also shows setups and measurements with some typical waveforms tested in the RTG4 DevKit, to provide confidence that the solutions do work in hardware.

2. 時鐘信號進入 SerDes 模塊參考時鐘輸入管腳，該管腳輸入參考時鐘，供片上專用高速 SerDes 模塊使用。

在這兩種類型的時鐘輸入中，RTG4 REFCLK 輸入將在本應用筆記中進行檢查。 RTG4 REFCLK 輸入可由 FPGA 設計人員編程為各種接收器類型之一（差分或單端信號），并且每個都具有邏輯電平要求，需要直接接口或轉換接口電路連接才能在與標準時鐘驅動器。此處未介紹為 RTG4 數字結構（上述類型“1”）提供時鐘輸入的信息，但它可以與標準驅動器時鐘連接，就像為 RTG4 REFCLK 接收器提供時鐘輸入一樣。
