ICS554-01

External Components

The ICS554-01 requires a decoupling capacitor of 0.01

µF to be connected between VDD on pin 2 and

GND on pin 7, as well as between VDD on pin 15 and GND on pin 10. These decoupling capacitors should

be placed as close to the device as possible. A 0.01

µF capacitor must be placed between the RES (pin 16)

and Ground, also, a resistor must be connected between the RES (pin 16) and VDD. Another eight

resistors are needed for the PECL outputs as shown on the block diagram on page 1. Suggested values of

these resistors are shown in the Block Diagram, but they can be varied to change the differential pair

output swing, and the DC level. Refer to Application Note, MAN09.

To achieve the low output skews that the ICS554-01 is capable of, careful attention must be paid to board

layout. Essentially, all 8 outputs must have identical terminations, identical loads, and identical trace

geometries. If they do not, the output skew will be degraded. For example, using a 30

Ω series termination

on one output (with 33

Ω on the others) will cause at least 15ps of skew.

Absolute Maximum Ratings

Stresses above the ratings listed below can cause permanent damage to the ICS554-01. These ratings,

which are standard values for ICS commercially rated parts, are stress ratings only. Functional operation of

the device at these or any other conditions above those indicated in the operational sections of the

specifications is not implied. Exposure to absolute maximum rating conditions for extended periods can

affect product reliability. Electrical parameters are guaranteed only over the recommended operating

temperature range.
