Quad Port Auto MDI/MDIX 10/100Base-T Transformer Isolation Modules
Features
• Designed for Broadcom BCM5226/5228, Level One LXT9784/
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
• Modules meet requirements of IEEE 802.3u and ANSI X3.263
• 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.
