Introduction
Q Two-chip modem solutions:
— DP2xxx in 48-pin TQFP.
— CSP1034S in a 48-pin TQFP package or
CSP1035A in a 48-pin TQFP package.
Q Data mode capabilities range:
2400 bits/s—56000 bits/s.
Q FAX mode capabilities range:
2400 bits/s—33600 bits/s.
Q Integrated DP2V data pump device:
— Integrated DSP and interface device.
— ISA-like microcontroller interface.
— Call progress speaker driver.
— Internal PLL allows low-speed crystal.
The new DP2 family of devices is designed to serve
embedded applications such as FAX machines and
set-top boxes in which a separate modem microcon-
troller is not required, e.g., where a suitable system
controller is already available to perform protocol
processing. The DP2 family includes the following
five devices:
Q DP2L17X supports V.17/V.29 (and lower) FAX
modes.
Q DP2L34D supports V.34 data and V.17/V.29
(and lower) FAX modes.
Q DP2L34X supports V.34 FAX as well as V.17/V.29
(and lower) FAX rates for FAX-only applications.
Q Compatible with transformer-based and silicon
