G.Lite ADSL Analog Front End IC
CONFIDENTIAL
Preliminary Information (Rev.1.0)
1.
OVERVIEW
This chapter provides an overview of the S5N8943B01 ADSL ATU-C & ATU-R
Analog Front End Chip.
1.1
Descriptions
General
The S5N8943B01 is Analog Front End IC designed for DMT based universal
ADSL(Asymmetric Digital Subscribe Line) modems with 0.35u fully CMOS
technology.
It has 25.875 ~ 138KHz Upstream channel and 142.312 ~ 552KHz bandwidth
Downstream channel. The S5N8943B01 includes AGC, LPF, ADC, DAC. The
AGC has 42dB gain 0.4dB step in RX mode and –24dB gain 2dB step in TX
mode with 12bit/8bit control bits. Anti alias LPF has 552KHz passband
frequency in RX path and 138KHz in TX path. Samsung’ s ADSL AFE chip
provides 14bit ADC at 2.208M, 4.416M or 8.832M sample rates and 14bit
4.416MHz, 8.832MHz DAC.
An 10bit DAC support VCXO control for timing recovery. The VCXO is divided
into a crystal driver at 35.328MHz.
