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
D3_cold 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.
