The Analog Devices AD9853AS is a highly integrated digital modulator device designed for applications requiring direct digital synthesis (DDS). It combines a high-speed DDS, a 10-bit high-performance DAC, digital filters, and other DSP functions onto a single chip.
Key features include a 165 MHz internal reference clock capability, 10-bit resolution, and a 32-bit output frequency tuning word. The device supports multiple modulation formats such as FSK, QPSK, DQPSK, 16-QAM, and D16-QAM. It offers a spurious-free dynamic range (SFDR) of greater than 50 dB at 42 MHz output frequency.
Designed for universal low-cost solutions in HFC networks, the AD9853AS also functions as a return-channel transmitter. It operates over a temperature range of -40°C to 85°C and is available in a space-saving 44-MQFP surface mount package.
This device is fabricated on an advanced CMOS process and provides a direct interface to cable driver amplifiers. It is suitable for HFC data, telephony, video modems, and wireless LAN applications. Note that this product is marked as obsolete.
The AD9853AS operates on a 3.3V to 5V single supply.
The operating temperature range is -40°C to 85°C.
The RoHS status is RoHS3 Compliant.
The AD9853AS is available in a 44-MQFP (10x10) surface mount package.
The AD9853AS has a resolution of 10 bits.
The internal reference clock frequency is 165 MHz.
The SFDR is greater than 50 dB.
