ES2839/ES2840 V.90/V.92 PCI HSP Modem Solution Product Brief DESCRIPTION The ES2839/ES2840 is a high-performance, two-chip, host- based 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 ® 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 battery- operated devices. The ES2839 includes a PCI bus interface, codec, and low- voltage, 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 line- monitoring 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 industry- standard 20-pin super small outline pack (SSOP) package.
