Quad Port Auto MDI/MDIX 10/100Base-T Transformer Isolation Modules  
Features  
• DesignedforBroadcomBCM5226/5228, LevelOneLXT9784/  
9785 and Kendin KS8995/8995E chipsets  
• Low profile (5.8mm) and light weight (4.5 g) 10/100Base-T  
Quad Port isolation transformer modules designed for Auto  
MDI/MDIX applications  
• ModulesmeetrequirementsofIEEE802.3uandANSIX3.263  
• SMD packages facilitate pick and place compatability and  
speed of placement while providing consistant and reliable  
coplanarity  
• Manufactured in an ISO-9001:2000, TS-16949:2002  
and ISO-14001:2004 certified Talema facility  
• Fully RoHS compliant and meets lead free reflow  
level J-STD-020C  
Electrical Specifications @ 25°C  
Inductance: 350µH minimum @ 100kHz, 100mV, 8mA  
Leakage Inductance: 0.4µH @ 1MHz  
Minimum isolation voltage: 1500 Vrms  
Operating Temperature Range: -40°C to +85°C  
Storage Temperature: -40°C to +125°C  
Standard packing: Tape and reel  
Quality and consistency is guaranteed through 100% testing of the specified parameters for primary inductance, leakage  
inductance, turns ratio, DC resistance and interwinding capacitance.This ensures that the return loss and pulse wave shape  
requirements can be fully maintained. Additionally, all parts are tested for 1500V minimum isolation.  
Applications  
Talema 10/100BaseT Quad transformer modules contain transmit and receive isolation transformers to maintain consistant  
wave shape and suppression of common mode noise while providing equipment isolation per IEEE 802.3. High impedance  
common mode quad chokes for additional EMI suppression have been added on some models as required for FCC and  
CISPR 22 Class B certification.
