ES2841/ES2840
PCI Integrated LAN V.90/V.92 Modem
Product Brief
DESCRIPTION
The ES2841/ES2840, ESS Technology’s first LAN plus hostbased TeleDrive modem chip for the PCI bus, provides desktop
and notebook computers with greater connectivity to both
packet networks and telephone networks. The ES2841/
ES2840 solution uses a solid-state DAA instead of a traditional
transformer DAA. The chipset consists of the ES2841
LAN modem chip and the ES2840, its accompanying highvoltage, solid-state DAA device. The ES2841 maximizes
integration and reduces the external component BOM cost to a
minimum.
The ES2841 device combines into a single-chip a host-based
V.90/V.92 modem, modem control buffers, modem codec, and
an IEEE 802.3-compatible Ethernet media access controller
(MAC) with an analog phoneline interface and a PCI bus
interface. This advanced high-level device integration allows the
ES2841 to be used as a host-based modem and LAN solution for
desktop and notebook systems requiring either a modem
connection or a 10/100 Ethernet connection. The ES2841 is also
capable of providing a home network connection that complies
with the Home Phoneline Networking Alliance (HomePNA) 1-Mb/
s (HPNA1.0) specification.
The ES2841 LAN feature supports 100BASE-TX (100-Mb/s
mode) and 10BASE-T (10-Mb/s mode) full-duplex operations.
The ES2841 includes a media independent interface (MII) and
reduced MII (RMII), enabling it to interface with an external PHY
transceiver used for either a LAN or HPNA-based chipset.
The ES284 modem sends and receives data and fax information
and supports the telephone answering machine (TAM) feature.
With its built-in ACPI D3
cold
wake on-LAN and wake on-ring
support, the ES2841 is an ideal modem solution for notebooks
and battery-operated devices. The ES2841 modem provides the
interface and control logic needed to transfer data between its
serial I/O terminals and the PCI interface.
The ES2841 delivers a high modem connectivity rate and high
throughput without the need of a dedicated DSP. It also
integrates a low-voltage, solid-state DAA that supports both
worldwide homologation and data/fax/voice call discrimination.
With the addition of an external high-voltage, solid-state DAA,
the ES2841 provides a very cost-effective modem/LAN solution
for add-on card, motherboard, and mini-PCI card
implementations.
The ES2840 high-voltage DAA device handles the line
monitoring and filtering functions, while also protecting the
signaling characteristics, performing all of the AC and DC
functions and interfacing with the line side of tip and ring
operations.
The ES2841 is available in a 128-pin low-profile quad flat pack
(LQFP) package. The ES2840 is available in an industry
standard 20-pin super small outline pack (SSOP) package.
