製品概要

HMCAD1102 is a high performance low power octal analog-to-digital converter (ADC). The ADC is based on a proprietary structure and employs internal reference circuitry, a serial control interface and serial LVDS output data. Data and frame synchronization output clocks are supplied for data capture at the receiver.

Various modes and configuration settings can be applied to the ADC through the serial control interface (SPI). Each channel can be powered down independently and data format can be selected through this interface. A full chip idle mode can be set by a single external pin. Register settings determine the exact function of this external pin.

There are two options for the serial LVDS outputs, 12- bit or 14-bit. In 12-bit mode, the LSB bit from the ADCs are removed in the output stream. In 14-bit mode, a ‘0’ is added in the LSB position.

The HMCAD1102 is designed to easily interface with field-programmable gate arrays (FPGAs) from several vendors.

The very low start up times for the HMCAD1102 allows significant power reduction in duty-cycled systems, by utilizing the Sleep Modes or Power Down Mode when the receive path is idle.
