ASD Introduces a New Family of Analog-to-Digital Converters

Trondheim, Norway, 31 March - Arctic Silicon Decices AS (ASD), the ultra low power mixed mode chip company, today introduced a new set of octal 12-bit Analog-to-Digital Converters, the GLACIER family.
This family of products is tailored to meet the strong demand for power reduction in high
performance applications as Medical Ultrasound and in Multiple Antenna Radio Systems such as
the emerging standards for wireless communication and Distributed Antenna Systems (DAS).

“The GLACIER family strengthens ASD’s leadership position in ultra low power ADC products”,
says Olav Lindquist, VP Sales and Marketing with ASD. The company brought to market their first
family of low power, standard ADCs, the SNOWFLAKE family, in November last year. The new
products now being introduced are based on this first platform, and add complexity such as
integration of 8 channels and high-speed LVDS outputs.

“With the GLACIER family we prove that the success achieved with the SNOWFLAKE family can be
replicated into more complex products”, Lindquist continues.

The GLACIER family consists of 8 channel 12-bit ADCs, speed graded at 20 -, 50 -, 65 -, and 80
MSPS. Both 12-bit and 14-bit LVDS output modes are available and can be selected through the
SPI control interface. Noise performance (SNR) at 50 MSPS with 8 MHz input frequency and 14-
bit output is 72.2 dB (typ) and 71 dB (worst).
Power dissipation at 50 MSPS is 40 mW per channel, including LVDS outputs.
The GLACIER family has a Power Down Mode with typically less than 10 μW power dissipation and
an unprecedented wake-up time of 18 μs. In addition, there is a Sleep Mode with 0.5 μs wake-up
time, and power dissipation in Sleep Mode is 3 mW per channel. These idle modes allow the user
to further reduce the average power dissipation by switching off the converter during idle periods.
“We have seen system designs where use of the GLACIER idle modes can reduce the average
power dissipation down to one quarter of active power dissipation. Starting from the ultra low
power dissipation of the GLACIER converters, and reducing it even further with the idle modes,
gives tremendous impact in systems where power dissipation is critical” Lindquist adds.

The GLACIER family consists of different versions of the part number ASD1000, which are pin
compatible with the ADS527x and ADS528x families from Texas Instruments. Later versions will
also include pin compatibility with AD9222, AD9212 and AD9252 from Analog Devices.

For all product versions, samples and evaluation boards are now available, and mass production
parts can be ordered from mid of June. The products come in a 64 pin QFN package.
