MINIMUM DATA TRANSITIONS

The CLC014 specifies a minimum transition rate. For the

CLC014 this sets the minimum data rate for transmitting data

through any cable medium. The CLC014 minimum average

transition density is found in the Electrical Characteristics

section of the datasheet.

POWER SUPPLY OPERATION AND THERMAL

CONSIDERATIONS

The CLC014 operates from either +5V or −5.2V single sup-

plies. Refer to Figure 1 when operating the part from +5V.

When operating with a −5.2V supply, the V

EE pins should be

bypassed to ground. The evaluation board and associated

literature provide for operation from either supply.

Maximum power dissipation occurs at minimum cable

length. Under that condition, I

CC =58mA.

Total power dissipated:

T = (58 mA)(5V) = 290 mW

Power in the load:

L = (0.7V)(11 mA) + (37.5)(11 mA)

2 =12mW

Maximum power dissipated on the die:

DMAX =PT–PL = 278 mW

Junction Temperature =

(

JA)(278 mW) + TA =T A + 26˚C
