Am79231 Data Sheet
LINECARD PARTS LIST
The following list defines the parts and part values required to meet target specification limits for
channel i of the linecard (i = 1, 2, 3, 4).
Notes:
1. Value can be adjusted to suit application.
2. Can be looser for relaxed ring-trip requirements.
3. Required for metering > 2.2 Vrms, otherwise may be omitted.
4. DT2i is optional - Should be put if there is a chance that this chip may be replaced by Am79R251.
