Bit Name
Function
15 PWM PWM Mode.
0 = Normal. Classic PWM output waveform.
1 = Scrambled mode. Low-distortion mode if used with output circuit shown in “AN70: Si2456/
Si2433/Si2414/Si2403 Modem Designer’s Guide”.
14 PWMG PWM Gain.
0 = No gain.
1 = 6 dB gain applied to AOUT.
13
PDN Powerdown.
Completely powerdown the Si2403 and Si3015. Once set to 1, the Si2403 must be reset to
power on.
0 = Normal.
1 = Powerdown.
12:8 Reserved Read returns zero.
7:5 Reserved Must not change in a read-modify-write.
4
PDL* Powerdown Line-Side Chip.
0 = Normal operation.
1 = Places the Si3015 in powerdown mode.
3:0 Reserved Must not change in a read-modify-write.
*Note: Typically used only for board-level debug.
