PeakADSL (TM) Quad Analog Front End
Tioga’s PeakADSL (TM) TA2040 Quad-AFE is designed to interface seamlessly
with Tioga’s TA1080 Octal ADSL transceiver chip.
It embodies four independent analog transmit and receive channels supporting
G.dmt and G.lite. Each channel contains a 15-bit DAC with associated
anti-imaging filters, a 15-bit ADC with anti-aliasing filter and a programmable
gain-summing amplifier (PGA). All analog signal paths are differential. A
clock multiplier and bandgap references are incorporated on-chip. A parallel
data interface allows for high-speed data transfer of the transmit/receive
data, while a serial interface is provided for control and configuration.
Integrated transmit interpolation filters reduce the data rate required to
be provided by the modem, thus, saving interface pins and power while maintaining
the benefits of using a faster DAC update rate.
- Integrates four complete full-rate ADSL Analog Front Ends (AFEs) on
