IC side terminated in 27 Ω S553-6500-C4 Line Side IC Side 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. -40 to +85° C dB min 1 1:2 31 2 3 1:2 4 5 16 22 21 1:2 20 19 14 15 24 23 1:2 12 13 26 25 1:2 10 11 28 27 1:2 8 9 30 29 1:2 6 7 32 1:2 18 17 ©2001 Bel Fuse Inc.
