AWR2243: AWR2243 的DEMO设计与CHECKLIST不一致

Part Number: AWR2243

 2243 DEMO  与 CHECKLIST 不一致点,以哪个为准:

1.SYNCIN 下拉电阻因该为多少

    

   DEMO   设计 10K下拉

SYNCIN

100K pull down to GND 

N10

100K pull down to GND

 

CHECKlist 要求: 100K

2.VIN_SRAM    VIN_SRAM的去耦电容


DEMO设计0.1uF

VNWA

Connect to 1.2V

P14

0.22 uF decap

VIN_SRAM

Connect to 1.2V

R14

0.22 uF decap

CHECKlist  要求:  0.22uF

 

  1. 我们用LP87524供电的时候,用的内部LDO bypass 模式,VOUT_PA对应的这个0R电阻 (DEMO 中的R87) 过电流是多少?
