The B0726-E and C1350-A ADSL transformers have

been approved by Broadcom for use with their BCM6335,

BCM6338, BCM6345, and BCM6348 ADSL CPE Mo-

dem chipsets and their BCM6301 5-Volt Line Driver.

These transformers feature split windings for chip re-

ceive, chip transmit and line side. They offer 1875 Vrms

1. Inductance measured at 10 kHz, 0.1 Vrms, 0 Adc between pins 9 and 16 with pins 11 and 14 connected.

2. Leakage inductance measured at 100 kHz, 0.1 Vrms between pins 9 and 16 with all other pins shorted.

3. Capacitance tested between pins 1 and 16 with all other pins shorted.

4. Total harmonic distortion measured at 30 kHz.

5. Operating temperature range −40°C to +85°C.

6. Electrical specifications at 25°C

Terminations:

Tape and reel: 200/13″ reel 44 mm tape width
