CXB1454R

Micro Strip Line

For maximum performance, the impedance between the pins SDDATAP/N of the LSI and the footprint of the

connector should be 50Ω using a micro strip line. 50Ω impedance can be reached when using 0.5mm width

pattern lines on L1 using this circuit board structure. The length of the lines should be identical and through-

hole should not be used. L2 is recommended as the large ground plane.

Terminators

Terminators (100Ω resistor) should be located as close to the LSI as possible.

Filter Devices and Reference Registors

Capacitors and resistors which are connected to LPFA/B and REXT are filters and reference resistors. The

region of Layer 2 (L2) is under the device and conductive patterns. The ground plane should be taken off in

order to reduce parasitic capacitors.

Bypass Capacitors

Bypass capacitors (0.1µF SMD type) should be located as close to the pins as possible. Refer to the

recommendation.
