80 MSP 14-bit ADCs with JESD204A serial
interface from ADI
Analog Devices has released the AD9644 dual and AD9641
14-bit 80MSPS (mega samples per second) ADCs, a pair of
low-power, high-speed 14-bit ADCs (analog-to-digital converters)
that incorporate the JESD204A data converter serial interface
standard. According to ADI these ADCs use half the power
of competing products and 25 percent less board area.
The JESD204A industry serial interface standard reduces
the number of data inputs/outputs between data converters
and other devices, such as FPGAs (field-programmable gate
arrays). This serial interface enables a range of high-speed
applications, including portable instrumentation, ultrasound
equipment, radar, wireless infrastructure (GSM, EDGE, W-CDMA,
LTE, CDMA2000, WiMAX, TD-SCDMA), and software-defined radios.
The key features of AD9644 Dual and 14-bit 80MSPS with
JEDS204A Interface include:
1. The AD9644 consumes 423mW at 80 MSPS and features a
multi-stage, differential-pipelined architecture with integrated
output error correction logic.
2. At 70 MHz and 80 MSPS, the AD9644 achieves an SNR (signal-to-noise
ratio) of 73.7 dBFS and an SFDR (spurious-free dynamic range)
of 92 dBc.
3. Supports up to 1.6 Gbps per link.
4. Offers two output modes supporting a dedicated data link
per ADC channel or a single shared data link for both ADC
channels.
5. Wide bandwidth differential sample-and-hold analog input
amplifiers support a variety of user-selectable input ranges
while an integrated voltage reference eases design considerations.
6. A duty cycle stabilizer is provided to compensate for
variations in the ADC clock duty cycle,
7. This device is specified over the industrial temperature
range of -40°C to +85°C.
