DESCRIPTION
ES2839/ES2840 V.90/V.92 PCI HSP Modem Solution Product Brief
FEATURES
* V.90/V.92 analog data/fax/TAM modem * Data mode capabilities:
--- --- --- --- V.90/V.92: 56 kbps ITU-T V.34: 33.6 kbps and fallbacks ITU-T V.17, V.29, V.27ter, and V.21ch2 Group 3 (TIA/EIA-578 Class 1 and Class 2)
The ES2839/ES2840 is a high-performance, two-chip, hostbased modem solution that delivers high connectivity and throughput, using a solid-state DAA instead of a traditional transformer DAA. The chipset consists of the ES2839 TeleDrive(R) modem chip and the ES2840, its accompanying high-voltage, solid-state DAA device. Together, the ES2839 and ES2840 devices comprise a very low-cost modem solution for add-in cards, desktops, and notebooks. The ES2839 modem is capable of send/receive data and fax, supports telephone answering machine (TAM), and is capable of data/fax/voice call discrimination. With its built-in ACPI and D3cold wake-on-ring support, the ES2839, plus the ES2840, forms an ideal modem solution for notebooks and batteryoperated devices. The ES2839 includes a PCI bus interface, codec, and lowvoltage, solid-state DAA. It also includes ADC and DAC conversions of modem/voice signal data and provides the interface and control logic needed to transfer data between its serial I/O terminals and the PCI interface. The ES2840, the high-voltage DAA device, handles the linemonitoring and filtering functions, while also protecting the signaling characteristics, performing all AC and DC functions, and interfacing with the line side of tip and ring operations. The ES2839/2840 modem solution meets all requirements for Microsoft WHQL certification, as well as V.250, V.251, and V.253 commands The ES2839 is available in a 100-pin low-profile quad flat pack (LQFP) package. The ES2840 is available in an industrystandard 20-pin super small outline pack (SSOP) package.
