• Manufacturer Part Number: z02215
• Description: Single Chip Modem With Integrated Controller, Data Pump, And Analog Front End
• Manufacturer: ZiLOG Semiconductor

Analog Inputs: Type AI
PS001907-0904
Description
Input impedance of transformer interface
3 dB point of transformer interface
External integration capacitance Type NPO
(COG)
Note: NPO and COG are synonymous terms for an industry standard dielectric material used for ceramic capacitors
which provides a very low temperature coefficient of capacitance (
capacitance (under 0.01% per Volt). It also has a low dissipation factor (0.1% max at 1 MHz for the values of
interest).
