CML's Low Power Wireline Modem products are employed worldwide in all types of communication applications.
CML's highly integrated ICs demand very little power or µC assistance, a factor that often means that the products can be line powered.
The wireline data IC range covers most relevant ITU-T V recommendations and compatible Bellcore data specifications. These single chip wireline data products offer a full suite of wireline signalling functions to cater for complete system operations from line and call set-up right through to the completed data transaction.
