what is the appropriate ground connection for the VCCD_PLL pins? None of these have GND pins nearby in the E22 package, but the name suggests that this is a digital pin, so it is referenced to the digital GND. So far, I've connected these to VCCINT through a 1uH inductor and ...
而应该是模拟部分的pll本身 又 分成了 模拟供电VCCA和数字供电VCCD_PLL，不是很明白？
(a) With VCCINT = 1.2V, the noise maximum noise ripple allowed on VCCD_PLL = 3% of VCCINT = 36mV. If I maintain a 10mV ( much less than 36mV) noise ripple across the power plane, can't I power both VCCINT and VCCD_PLL with the same power plane without using any isolation fil...
with a Vccio=1.8 (the bank 7 & 8 are used for DDR2 memory interface), additionally the designer use others some pins of these banks to connect a clock input CLKIN_66 (3.3v) , user switch (USER_DIPSW3) and user push button (USER_PB3) , both with vcc=2.5...
I am currently using a Altera FPGA (EP3C16F484C8N). I need to provide 1.2V to the VCCD_PLL and VCCINT pins. I would like to know the acceptable noise level (Vrms) to those pins. Subscribe More actions MGane2 Beginner 10-26-2018 01:11 PM 1,331 Views...
Cyclone 10LP device migration fom a 10MDAF256C to a larger device with 4 PLL's. Can the no connect pins D4 and N13 (vccd_pll3 and vccd_pll4) be connected to 1.2 volts on a 10MDAF256C device? 訂閱 更多動作 HMuld1...
1,227 Views Want to ask if PowerPlay Analyzer includes currents consummed by V_CCA and V_CCD in I_CCINT? In particular I am interested in Cyclone II series, that does not provide static (standby) currents ICCA and ICCD in datasheets. ...
