LG1605DXB Limiting Amplifier

Mounting and Connections (continued)

Lucent Technologies/FORCE ICs assembly procedure recommendations for the LG1605DXB are as follows:

s Board solder pattern for the 1605DXB package base should not exceed 50% of the package base area.

s Back lighting can be used during the pick and place operation to silhouette the package in order to eliminate

reflection problems with the solder on the bottom.

s Set the lead spacing tolerance to ±0.012 in.

s Insertion pressure should not exceed 125 g.

Electrical Characteristics

tCASE = 0 °C to 70 °C, VBR = –1.5 V, VSS = –4.7 V to –5.7 V, bit rate = 2.488 Mbits/s NRZ, and data pattern =

223 – 1 PRBS, unless otherwise indicated.

Note: Minimum and maximum values are testing requirements. Typical values are characteristics of the device and

are the result of engineering evaluations. Typical values are for information purposes only and are not part of

the testing requirements.
