Clock Generators, PLLs, Frequency Synthesizers datasheet and documents for MAX9485ETP+

MAX9485ETP+

Clock Generators, PLLs, Frequency Synthesizers Overview

The MAX9485ETP+ is a programmable audio clock generator designed for MPEG-2 audio systems. It accepts a 27MHz reference input and generates buffered clock outputs at 256, 384, or 768 times the selected sampling frequency (12kHz to 96kHz). The device features an integrated VCXO with ±200ppm tuning range and low jitter of 21ps RMS at 73.728MHz. It operates on a single 3.0V to 3.6V supply, consuming 12mA typical current. The ET suffix denotes the Thin QFN-EP package, suitable for -40°C to +85°C operation.
