Using the IDT CMOS Oscillator technology, originally developed by
Mobius Microsystems, the MM8202 replaces quartz crystal based
resonators and oscillators with a monolithic CMOS IC at the thinnest
possible form factors without the use of any mechanical frequency
source or PLL. The product is specially designed to work with the
next generation USB 2.0 High Speed, USB 2.0 Full/Low Speed and
USB-IC (USB-InterChip) interface controller ICs, and high density
SIM-, and smart-cards.
Features
• All-CMOS Temperature Compensated Oscillator
• TimeStak
TM
: Available in die form for the thinnest and smallest
MCP options (-D package option)
• Ultra-low power operation (2mA typical at 1.8V supply)
• No quartz or PLL used: very low jitter performance leading to low
link Bit Error Rates (BER)
• Excellent reliability: Shock and vibration resistant
• Many frequencies are supported
• Factory programmable from 6 to 133MHz
