Transformer Selection Guide |
|
Customers of Cologne Chip can choose from a variety of transformers.
For ISDN S/T Basic Rate Interface, all ISDN S/T transformers are compatible to the HFC-S and XHFC series of Cologne Chip that fulfill two criteria:
1) Turns ratio of 1:2 (line side : chip side)
2) Center tap on chip side (required for Cologne Chip receiver circuitry)
For two-wire ISDN Up Basic Rate interface (Up0/UpN), all Up transformers are compatible to the XHFC series of Cologne Chip that have the following features:
1) Turns ratio of 1:1
2) Two separated windings (resp. a centre tap) on chip side (required
for Cologne Chip receiver circuitry)
For ISDN E1 Primary Rate Interface, all E1 transformers are compatible to the HFC-E1 that fulfill two criteria:
1) Turns ratio of 2.4:1 (line side : chip side) for transmit and 1:1 for receive path.
2) Center tap on chip side (required for Cologne Chip receiver circuitry)
Several companies provide transformers and transformer modules that can be used with our ISDN Basic Rate and Primary Rate Interface controllers. Most popular are SMD modules with chokes for EMI reasons. Part numbers and manufacturers are listed underneath. The "bestsellers" in terms of price-performance of some manufacturers are marked with an asterisk (*).
This cross-reference list has not been compiled under aspects of RoHS
compliance. For the current RoHS status of the listed parts, please
contact the transformer manufacturers straight.
Please note: Cologne Chip cannot take any liability concerning the product names, characteristics and availability. All information presented is based upon manufacturer's statement. Products can change without notice. Please refer to the manufacturer in case of doubt.
