IP4251/52/53/54-TTL Nexperia Integrated 4-, 6- and 8-channel passive filter network 6.2 Selection The selection of one of the filter devices has to be performed depending on the maximum clock frequency, driver strength, capacitive load of the sink, and also the maximum applicable rise and fall times. 6.2.1 SDHC and MMC memory interface The Secure Digital High Capacity (SDHC) memory card interface standard specification and the Multi Media Card (MMC) (JESD 84A43) standard specification recommend a rise and fall time of 25% to 62.5% (62.5% to 25% respectively) of 3ns or less for the input signal of the receiving interface side. Assuming a typical capacitance of about 20pF for the SDHC memory card itself, and approximately 4pF to 7pF for the Printed-Circuit Board(PCB) and the card holder, IP4252CZ12-6-TTL (6channels, R =40Ω, C =12pF at V =2.5V) is a s(ch) ch bias(DC) matching selection to filter and protect all relevant interface pins such as CLK, CMD, and DAT0 to DAT3/CD. Please refer to Figure7 for a general example of the implementation of the device in an SDHC card interface. In case additional channels such as write-protect or a mechanical card-detection switch are used, the IP4252CZ16-8-TTL (8channels, R =40Ω, C =12pF at s(ch) ch V =2.5V) offers two additional channels. bias(DC) IP4251_52_53_54-TTL All information provided in this document is subject to legal disclaimers. © Nexperia B.V. 2017.

Example of IP4252 in an SDHC card interface The capacitance values specified for the signal channels of the MMC interface differ from the SDHC specification. The MMC card-side interface is specified to have an intrinsic capacitance of 12pF to 18pF and the total channel is limited according to the specification to 30pF only. Therefore, any filter device capacitance is limited to a maximum of up to 18pF, including the card holder and PCB traces. Please refer to Figure8 for a general example of the implementation of the IP4252 in an MMC interface application.

Example of IP4252 in an MMC interface To generate SDHC and MMC-compliant digital signals, the driver strength should not significantly undercut 8mA. 6.2.2 LCD interfaces, medium-speed interfaces For digital interfaces such as LCD interfaces running at clock speeds between 10MHz and 25MHz or more, IP4251, IP4252 or IP4254 can be used depending on the sink load, clock speed, driver strength and rise and fall time requirements. Also the minimum EMIfilter requirements may be a decision-making factor. 6.2.3 Keypad, low-speed interfaces Especially for lower-speed interfaces such as keypads, low-speed serial interfaces (e.g.Recommended Standard(RS) 232) and low-speed control signals, IP4253(R =200Ω, C =30pF at V =2.5V) offers a very robust s(ch) ch bias(DC) ESDprotection and strong suppression of unwanted frequencies (EMI filtering).
