PEB3265 Infineon Technologies Corporation, PEB3265 Datasheet - Page 119

• Manufacturer Part Number: PEB3265
• Description: (PEB326x / PEB426x) Dual Channel Slicofi-2 / Slic Duslic
• Manufacturer: Infineon Technologies Corporation

Preliminary
This setting results in a receive gain of 11.88 dB caused by the internal filters. Based on
this a factor K
Transversal current I
R
K
V
K
In order not to overload the analog input, the maximum AC transversal current may not
be higher than 9 mA rms.
Usage of Tone Generator as Signal Source
To simplify the formulas, the programmable receive and transmit gain is disabled.
This is done by setting the following bits:
Register BCR4:
Register TSTR4:
Register LMCR1: TEST-EN = 1
The tone generator level is influenced by a factor K
coefficients. The internal filter attenuation is 2.87 dB.
