HMCAD1511
High Speed Multi-Mode 8-Bit
30 MSPS to 1 GSPS A/D Converter
General Description
The HMCAD1511 is a versatile high performance low power analog-to-digital converter (ADC), utilizing time-interleaving
to increase sampling rate. Integrated Cross Point Switches activate the input selected by the user.
In single channel mode, one of the four inputs can be selected as a valid input to the single ADC channel. In dual
channel mode, any two of the four inputs can be selected to each ADC channel. In quad channel mode, any input can
be assigned to any ADC channel.
An internal, low jitter and programmable clock divider makes it possible to use a single clock source for all operational
modes.
The HMCAD1511 is based on a proprietary structure, and employs internal reference circuitry, a serial control
interface and serial LVDS/RSDS output data. Data and frame synchronization clocks are supplied for data capture
at the receiver. Internal 1 to 50X digital coarse gain with ENOB > 7.5 up to 16X gain, allows digital implementation of
oscilloscope gain settings. Internal digital fine gain can be set separately for each ADC to calibrate for gain errors.
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 pin.
HMCAD1511 is designed to easily interface with Field Programmable Gate Arrays (FPGAs) from several vendors.
