1 / 4 page  ESS Technology, Inc. SAM0316-041101 1 ESS Technology, Inc. ES2838 V.90/V.92 PCI HSP Modem Product Brief DESCRIPTION The ES2838 is a high-performance, single-chip, host-based modem solution that delivers high connectivity and throughput without the need for a dedicated DSP. With the addition of an external transformer DAA, the ES2838 TeleDrive ® modem chip provides a very low-cost modem solution for add-in cards, desktops, and notebooks. The ES2838 modem is capable of send/receive data and fax and supports telephone answering machine (TAM), and is capable data/fax/voice call discrimination. With its built-in ACPI and D3cold wake-on-ring support, the ES2838 is an ideal modem solution for notebooks and battery-operated devices. The ES2838 includes a PCI bus interface and a codec. It also includes ADC and DAC conversion of modem/voice signal data and provide the interface and control logic needed to transfer data between its serial I/O terminals and the PCI interface. The ES2838 ADC and DAC operate synchronously so that data reception at the ADC channel and data transmission from the DAC channel occur during the same time interval. The ES2838 modem solution meets all the requirements Microsoft WHQL certification, as well as V.250, V.251, and V.253 commands. The ES2838 is available in a 100-pin low-profile quad flat pack (LQFP) package.
