adv7610能否配置pha_a/in2脚拉高

adv7610芯片是一种视频接口处理器，其工作原理涉及多个数字信号和模拟信号的输入和输出，包含众多配置选项。其中，PHA_A/IN2脚是其中之一。

在adv7610的设计中，PHA_A/IN2脚用于控制输入到芯片的视频信号的颜色空间。如果该脚被拉高，则输入信号将被认为是RGB颜色空间。否则，它将被认为是YCbCr颜色空间。

因此，对于是否可以配置PHA_A/IN2脚拉高，答案是肯定的。这可以通过编程接口或硬件设置进行设置。具体实现方法需要参考adv7610的技术文档和说明书进行详细了解。

值得注意的是，将PHA_A/IN2脚配置为拉高不一定总是为芯片的所有应用和场景最佳。在具体应用时，需要根据视频信号的特征和要求进行合适的配置选择，以达到最佳的输出效果。

[DRC PDRC-182] PLL_adv_ClkFrequency_div_no_dclk: The computed value 666.667 MHz (CLKIN_PERIOD, net nfc_clk) for the VCO operating frequency of the PLL site PLL_X0Y11 (cell design_1_wrapper_i/design_1_i/nfc_8ch_v_wrapper_1/inst/ch0_dqs_inst/inst/top_inst/clk_rst_top_inst/clk_scheme_inst/GEN_PLL_IN_IP_USP.plle4_adv_pll0_inst) falls outside the operating range of the PLL VCO frequency for this device (750.000 - 1500.000 MHz). The computed value is (CLKFBOUT_MULT * 1000 / (CLKIN_PERIOD * DIVCLK_DIVIDE)). Please adjust either the input period CLKIN_PERIOD (12.000000), multiplication factor CLKFBOUT_MULT (8) or the division factor DIVCLK_DIVIDE (1), in order to achieve a VCO frequency within the rated operating range for this device.

这是一条PDRC错误信息，指出PLL_X0Y11的VCO操作频率为666.667 MHz，超出了此设备PLL VCO频率的操作范围750.000-1500.000 MHz。要解决此问题，需要调整输入周期CLKIN_PERIOD（12.000000）、乘法因子CLKFBOUT_MULT（8）或除法因子DIVCLK_DIVIDE（1），以实现在此设备的额定操作范围内的VCO频率。

[Place 30-575] Sub-optimal placement for a clock-capable IO pin and MMCM pair. If this sub optimal condition is acceptable for this design, you may use the CLOCK_DEDICATED_ROUTE constraint in the .xdc file to demote this message to a WARNING. However, the use of this override is highly discouraged. These examples can be used directly in the .xdc file to override this clock rule. < set_property CLOCK_DEDICATED_ROUTE BACKBONE [get_nets sys_clk_IBUF] > sys_clk_IBUF_inst (IBUF.O) is locked to IOB_X1Y74 instance_name/inst/mmcm_adv_inst (MMCME2_ADV.CLKIN1) is provisionally placed by clockplacer on MMCME2_ADV_X1Y2 The above error could possibly be related to other connected instances. Following is a list of all the related clock rules and their respective instances. Clock Rule: rule_mmcm_bufg Status: PASS Rule Description: An MMCM driving a BUFG must be placed on the same half side (top/bottom) of the device instance_name/inst/mmcm_adv_inst (MMCME2_ADV.CLKFBOUT) is provisionally placed by clockplacer on MMCME2_ADV_X1Y2 and instance_name/inst/clkf_buf (BUFG.I) is provisionally placed by clockplacer on BUFGCTRL_X0Y31

Based on the provided information, it seems that there is a sub-optimal placement for a clock-capable IO pin and MMCM pair in your design. If this condition is acceptable, you can use the CLOCK_DEDICATED_ROUTE constraint in the .xdc file to demote the message to a WARNING. However, using this override is highly discouraged.

To override this clock rule, you can add the following line in the .xdc file:

set_property CLOCK_DEDICATED_ROUTE BACKBONE [get_nets sys_clk_IBUF]

Please note that this error could possibly be related to other connected instances. The related clock rule "rule_mmcm_bufg" seems to be passing, but it's important to review all the clock rules and their respective instances to ensure proper placement.
