DP2L34D
Features
Introduction
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 microcontroller 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:
Two-chip modem solutions:
- DP2xxx in 48-pin TQFP.
- CSP1034S in a 48-pin TQFP package or CSP1035A in a 48-pin TQFP package. Data mode capabilities range: 2400 bits/s- 56000 bits/s. FAX mode capabilities range: 2400 bits/s- 33600 bits/s. Integrated DP2V data pump device:
- Integrated DSP and interface device.
- ISA-like microcontroller interface.
- Call progress speaker driver.
- Internal PLL allows low-speed crystal. patible with transformer-based and silicon DAA circuits:
- High-precision sigma-delta codec (CSP1034S).
- Line-powered silicon DAA (CSP1035A). Caller identification (caller ID) support for Bell 202 and V.23 frequencies. Low-power...
