ADC07D1520
Low Power, 7-Bit, Dual 1.5 GSPS or Single 3.0 GSPS A/D Converter
General Description Features The ADC07D1520 is a dual, low power, high performance
CMOS analog-to-digital converter. The ADC07D1520 digitizes signals to 7 bits of resolution at sample rates up to 1.5
GSPS. Its features include a test pattern output for system
debug, a clock phase adjust, and selectable output demultiplexer modes. This device is guaranteed to have no missing
codes over the full operating temperature range. The unique
folding and interpolating architecture, the fully differential
comparator design, the innovative design of the internal sample-and-hold amplifier and the self-calibration scheme enable
a very flat response of all dynamic parameters beyond
Nyquist, producing a high 6.8 Effective Number of Bits
(ENOB) with a 748 MHz input signal and a 1.5 GHz sample
rate while providing a 10-18 Code Error Rate (C.E.R.) Output
formatting is offset binary and the Low Voltage Differential
Signaling (LVDS) digital outputs are compatible with IEEE
1596.3-1996, with the exception of an adjustable common
mode voltage between 0.8V and 1.2V.
Each converter has a selectable output demultiplexer which
feeds two LVDS buses. If the 1:2 Demultiplexed Mode is selected, the output data rate is reduced to half the input sample
rate on each bus. When Non-Demultiplexed Mode is selected,
the output data rate on channels DI and DQ is at the same
rate as the input sample clock. The two converters can be
interleaved and used as a single 3 GSPS ADC. …
