using a micro strip line. 50 ? 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 (100 ? 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 (0.1f smd type) should be located as close to the pins as possible. refer to the recommendation. 14 CXB1456R recommendation for cable and connector characteristics the gvif system uses terminators at both ends (transmitter and receiver), a cable equalizer and a small amplitude differential signal. in order to solve the problems of high speed data transmission such as signal reflection, reduce the signal level and emi. in order to achieve the best solution, note the following: tx lsi rx lsi tx termination 50 ? tx termination 100 ? microstrip line (50 ? ) microstrip line (50 ? ) foot print foot print cable (diff. 100 ? ) connector connector it is important to note the following issues for a good data transmission system: good impedance matching differential impedance should be fit to the recommended template on the next page. cable loss should be small and the loss curve should be smooth. maximum loss should be less than 6db at 1ghz. see the next page. skew of pos/neg (differential signal) should be small less than 12% of 1-bit time or 160ps@vga, 100ps@svga, 60ps@xga. good emi performance cable and connectors. in order to satisfy these issues, the recommendations are as follows: use the differential cable which provides good controlled impedance, low loss and good skew matching. a shielded twisted pair (stp) cable is recommended. use a low reflectance connector. to minimize interference from other signals, high speed signal lengths should be identical. use double shielded cable. 15 CXB1456R recommended transmission path : differential impedance template 150 zo ( ?
