DP2V90DX

www.DataSheet4U.com Product Brief Rev. 1 December 2004 DP2 Data Pump Chip Sets Features Q 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: 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. 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. Compatible 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 modes. Requires only a single 3.3 V supply. Six user-definable bit I/Os. Object code compatible with the DPV family. IEEE ® P1149.1 test port (JTAG boundary scan). All DP2xxx products are pin for pin compatible with the DP2V product line. Q Q DP2L17X supports V.17/V.29 (and lower) FAX modes. DP2L34D supports V.34 data and V.17/V.29 (and lower) FAX modes. DP2L34X supports V.34 FAX as well as V.17/V.29 (and lower) FA...
