T1/CEPT/ISDN-PRI Transformer Quad Port SMT Transformer Module with Line Side Protection Four transmit transformers, four receive transformers and line side protection circuit in a surface mount package Matched to Level One’s LXT384LE/BE Octal T1/E1 Transceiver Extended temperature range Patented “Interlock Base” construction for high reliability IC grade transfer-molded package withstands 235°C IR reflow temperature Minimum Isolation voltage: 1500 Vrms UL 1950 recognized Electrical Specifications @ 25°C — Operating Temperature -40°C to +85°C Turns Ratio1 OCL CW/W LL Package/ Pri:Sec (±2%) Line Side µH MAX) (pF MAX) ( Schematic Transmit Receive (mH MIN) Part Number T9030NL 1CT:2 1CT:1 1.2 35 & 35 .50 & .80 BRT Primary Pins Transmit Receive 4-6, 10-12, 16-18, 22-24 48-46, 42-40, 36-34, 30-28 1 For receive channel, to make a 1:2 ratio from a 1CT:1, use only one-half of the primary (1CT) winding. NOTE: For extended temperature range transformers, OCL (Open Circuit Inductance for the primary winding) is specified at both -40°C and +25°C. At -40°C, OCL is 600 µH minimum. All other parameters are specified at +25°C.
