isppac80 Lattice Semiconductor Corp., isppac80 Datasheet - Page 3

• Manufacturer Part Number: isppac80
• Description: In-system Programmable Analog Circuit
• Manufacturer: Lattice Semiconductor Corp.

Notes: (1) A wider input range of 0.7V to 4.3V is typical, but not guaranteed. Inputs larger than this will be clipped. Input signals are also subject
to common-mode voltage limitations. Refer to the table of conditions in this datasheet. (2) Refer to theory of operation section later in this datasheet
for explanation of differential voltage swing computation. (3) To insure full spec performance an additional auto-calibration should be performed
after initial turn-on and the device reaches thermal stability. (4) Although many hundreds of thousands of filter configurations are available using
ispPAC80, not every type will have corner frequencies available from exactly 50kHz to 500kHz, depending on the tables available from within PAC-
Designer filter design tools. The general specifications given under this heading are realized using the Elliptic filter types. Support for filter types
with corner frequencies from 500kHz to 750kHz is limited to the Butterworth family, as found in the filter database in PAC-Designer. For more
information on other types and/or frequencies not contained in the filter database, please contact Lattice Marketing. (5) A Cauer elliptic filter of type
CC051042 (see datasheet text) is used to guarantee these specific filter accuracy specifications. It is assumed that all other configurations available
in PAC-Designer will exhibit equivalent performance according to the applicability of the individual filter type. Necessary limitations will apply,
however, when specifications do not directly apply. See the data sheet text, application notes and guides in PAC-Designer for specific filter type
considerations.
