LM1893 LM2893 Carrier-Current Transceiver
General Description
Carrier-current systems use the power mains to transfer in-
formation between remote locations This bipolar carrier-
current chip performs as a power line interface for half-du-
plex (bi-directional) communication of serial bit streams of
virtually any coding In transmission a sinusoidal carrier is
FSK modulated and impressed on most any power line via a
rugged on-chip driver In reception a PLL-based demodula-
tor and impulse noise filter combine to give maximum range
A complete system may consist of the LM1893 a COPSTM
controller and discrete components
Features

Note 1 More accurately the maximum voltage allowed on pin 10 is VOC and VOC ranges from 41 to 50V Also transients may reach above 60V see the transient
peak voltage characteristic curve
Note 2 The maximum power dissipation rating should be derated for device operation above 25 C to insure that the junction temperature remains below the
maximum rating Use a iJA of 75 C W for the N package using a socket in still air (which is the worst case) Consult the Application Information section for more
detail
Note 3 The boldface values apply over the full junction temperature range for the specified supply voltage range All other numbers apply at TAeTJe25 C Pin
numbers refer to LM1893 LM2893 tested by shorting Carrier In to Carrier Out and testing it as an LM1893
Note 4 Guaranteed and 100% production tested
Note 5 Guaranteed (but not 100% production tested) over the temperature and supply voltage ranges These limits are not used to calculate outgoing quality
levels
Note 6 Total harmonic distortion is measured using THDe IRMS (all components at or above 2FO) IRMS (fundamental)
Note 7 Receiver function is defined as the error-free passage of 1 cycle of 50% duty-cycle 2 4 kHz square-wave data (2 sequential 208 mS bits) with the first bit
being a ‘‘1 ’’ All of the data transitions (edges) must fall within g10% (g20 8 ms) of their noise-free positions RX time delay is minimized by using no impulse noise
filter cap CI for this test
Note 8 During the sensitivity check note 7 requirements are followed with these exceptions (1) data rate FDATAe1 2 kHz (2) all of the data transitions must fall
within g20% (g41 6 ms) of their noise-free positions and (3) a time-domain filter capacitor (CI) is used The time delay of CI is bit or 208 ms (CI is
approximately 6200 pF)
Note 9 For TTL compatibility use a pull-up resistor to increase min VOH to above 2 8 V
