EMIF06-USD05F3 6-line EMI filter and ESD protection for SD card, mini-SD card and micro-SD card interfaces Description The EMIF06-USD05F3 is a 6-line EMI filter dedicated to SD, mini-SD and micro-SD card applications. It provides an efficient attenuation at 900 MHz to reduce or suppress the antenna de- sense. This filter includes ESD protection circuitry, which prevents damage to the protected device when inserting the card. Pull-up resistors Flip Chip are not integrated inside the chip, hence the (15 bumps) EMIF06-USD05F3 gives the flexibility to customers to use controllers with embedded Datasheet production data resistance. This 6-line IPAD is packaged into a flip-chip solution, saving PCB space. Features Figure 1.
