Note 1: The package is mounted on a four-layer JEDEC-standard test board.
Note 2: Theta-JA (
θJA) is the junction-to-ambient thermal resistance, when the package is mounted on a four-layer JEDEC-standard test board.
Note 3: While Theta-JC (
θJC) is commonly used as the thermal parameter that provides a correlation between the junction temperature (Tj) and
the average temperature on top center of the LQFP package (TC), the proper term is Psi-JT. It is defined by: (Tj - TC) / overall package
power.
Note 4: The method of measurement for the thermal parameters is defined in the EIA/JEDEC-standard document EIA-JESD51-2.

REVISION HISTORY
REVISION
DESCRIPTION
042303
New product release.
012104
Table 5-B. Receive Level Indication: Changed “-12.5 to -5.0” to “-12.5 to -15.0”. Adjusted steps
after -17.5 dB to be in -2.5dB decrements.
Section 9, Operating Parameters: Updated supply current and power dissipation values in the DC
Characteristics table to reflect latest characterization data. Updated Note 5 to show that values are for all ports
active.
113004
In the Absolute Maximum Ratings section, added range for storage temperature and changed
soldering temperature from IPC JEDEC J-STD-020A to J-STD-020.
011206
Added lead-free packages to Ordering Information table.
