V.90 Integrated Data/Fax/Voice/Speakerphone Modem Device Set
Chip 2: DM6581/DM6582 ITU-T V.90 TX
and RX Digital Signal Processor
Description
DM6581/82 Description
26
Preliminary
Version: DM560P-DS-P07
August 11, 2000
The DM6581/DM6582 are application specific Digital
Signal Processors (DSP) dedicated to V.90 modem
operation. They are used in pairs. The primary
component of these devices is a 22.43Mips DSP
core processor. The basic clock frequency of this
device is 40.32MHz. An internal built PLL circuit is
used to boost the clock from 40.32MHz to 80.64MHz
or 89.74MHz. This 80.64MHz/89.74MHz clock is
used as the clock source of DSP core processor. A
16-byte dual port SRAM is utilized to provide the
communication between DSP and the DM6583.
There are two dedicated serial ports that provide the
link between the DSP and the DM6580. The
DM6581/DM6582 are bonded-out in a 100-pin QFP
package for mass production, and provide the most
economical package.
