Various countries are expected to adopt the IEC
CISPR22 standard over the next few years. For
example, the European Union (EU) has adopted a
standard entitled EN55022, which is based on the
CISPR22 standard. Adherence to this standard will be
necessary to display the CE mark on designs intended
for sale in the EU. The typical schematic and global bill
of materials (BOM) (see Figure 6 and Table 7)
contained in this data sheet are designed to be
compliant to the CISPR22 standard.
If smaller inductors are desired, a notch filter may be
used and compliance to CISPR22 still achieved. As
shown in Figure 17, a series capacitor-resistor in
parallel with L1 and L2 forms the simple notch filter.
Table 14 shows corresponding values used for C24,
C25, C38, C39, L1, L2, R31, and R32.

The direct current resistance (DCR) of the listed
inductors is an important consideration. If the DCR of
the inductors used is less than 3 Ω each, then country
PTT specifications which require 300 Ω or less of dc
resistance at TIP and RING with 20 mA of loop current
can be satisfied with the Japan dc termination mode. If
the DCR of the inductors is at or slightly above 3 Ω, the
low-voltage termination mode may need to be used to
satisfy the 300 Ω dc resistance requirement at 20 mA of
loop current. In all cases, "4.9. DC Termination
Considerations" on page 17 should be followed.
If compliance to the CISPR22 standard and certain
other country PTT requirements are not desired, then
L1 and L2 may be removed. If these inductors are
removed, C24 and C25 should be increased to 2200 pF,
and C9 should be changed to 22 nF, 250 V. With these
changes, PTT compliance in the following countries will
not be achieved: India (I/Fax-03/03 standard), Taiwan
(ID0001 standard), Chile (Decree No. 220 1981
standard), and Argentina (CNC-St2-44.01 standard).
For questions concerning compliance to CISPR22 or
other relevant standards, contact a Silicon Laboratories
technical representative.
