Specifications subject to change without notice. 11.01 SCHEMATIC For 8 channel applications, minimum crosstalk is achieved when one S553-6500-C4 module is used for all receive interfaces and a second module is used for all transmit interfaces. No signal assignments are shown on the schematic as users have total flexibility to connect module as discussed above, or to alternate transmit and receive interfaces within a single module. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 Bel Fuse Inc. 206 Van Vorst Street, Jersey City, NJ 07302 * Tel 201-432-0463 * Fax 201-432-9542 * www.belfuse.com page 1 HIGH FREQUENCY MAGNETICS TM01118 T1/E1 Mini-Octal Transformer Module MECHANICAL Meets or exceeds all circuit requirements for: PMC Sierra PM4318 Intel LXT384, LXT386 Conexant CN8380 Exar XRT5997, XRT81L27, XRT82L24, XRT82L34, XRT82L38 S553-6500-C4 1.050 [26.67] max 0.050 [1.27] 0.425 0.300 [10.80] [7.62] max 0.050 [1.27] pitch 0.465 [11.81] 0.070 [1.78] 0.020 0.002 [0.51 0.05] 0.025 [0.64] R0.005 [R0.13] typ R0.005 [R0.13] typ 0.290 [7.37] max 0.004 0-5 0.750 [19.05] 0.010 [0.25] min 2X 0.035 [0.89] 2X 0.060 [1.52] Dimensions are in inches [millimeters].
