RFI Rejection
Figures 12—14 show the typical RFI rejection performance of the L8567 under the various conditions listed within
each figure title. The test circuit is shown below. The input signal is 100 kHz to 100 MHz, 1 Vrms and 2 Vrms, 80%
AM, with 1 kHz side tone applied using an R&S T network (CDN). This test is performed to the IEC 801-6 (1994)
specification. Note that all power supplies (V
CC
, V
DD
, V
BAT
) are bypassed to ground, as close as possible to the IC,
with 1 nF capacitors, and all grounds are shorted on the bottom of the board as close as possible to the IC. Note
that no RFI LP filter is used at tip and ring.
