Clock Generators, PLLs, Frequency Synthesizers datasheet and documents for MAX9485EUP+
Clock Generators, PLLs, Frequency Synthesizers Overview
The MAX9485EUP+ 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 (typical 21ps RMS at 73.728MHz). It operates on a 3.3V supply over the -40°C to +85°C temperature range and is housed in a 20-pin TSSOP package.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes
Verify the suffix 'EUP+' indicates the 20-pin TSSOP package variant. Confirm the extended temperature rating (-40°C to +85°C) matches the design requirements. Ensure the 3.3V power supply specification aligns with the target system voltage levels before procurement.
Clock Generators, PLLs, Frequency Synthesizers Selection Notes
Select this component when a low-jitter audio clock generator is required for MPEG-2 compliant systems. The TSSOP package is suitable for applications where board space allows for its 6.5mm x 4.4mm footprint. Consider the QFN variant if a smaller 4mm x 4mm profile is necessary.
Clock Generators, PLLs, Frequency Synthesizers Part Context
This part belongs to the MAX9485 family of programmable audio clock generators. The 'E' suffix denotes the extended industrial temperature range, while 'UP' specifies the 20-pin TSSOP package. The '+' suffix indicates lead-free compliance.
