Features
Benefits
EPROM-programmable die for in-package programming of
crystal oscillators
High resolution PLL with 12 bit multiplier and 10 bit divider
Enables quick turnaround of custom oscillators
Lowers inventory costs through stocking of blank parts
Enables synthesis of highly accurate and stable output clock
frequencies with zero or low PPM
Enables fine-tuning of output clock frequency by adjusting
C
Load
of the crystal
Enables reprogramming of programmed part, to correct errors,
and control excess inventory
Enables programming of output frequency after packaging
Lowers cost of oscillator as PLL can be programmed to a high
frequency using a low-frequency, low-cost crystal
Duty cycle centered at 1.5V or V
DD
/2
Provides flexibility to service most TTL or CMOS applications
Services most PC, networking, and consumer applications
EPROM-programmable capacitor tuning array
Twice programmable die
Simple 4-wire programming interface
On-chip oscillator runs from 10–30 MHz crystal
EPROM-selectable TTL or CMOS duty cycle levels
Operating frequency
—1–200 MHz at 5V
—1–100 MHz at 3.3V
—1–66.67 MHz at 2.7V
Sixteen selectable post-divide options, using either PLL or
reference oscillator output
Programmable PWR_DWN or OE pin
Programmable asynchronous or synchronous OE and
PWR_DWN modes
Low Jitter outputs
—< ±100ps (pk-pk) at 5V
—< ±125ps (pk-pk) at 3.3V
3.3V or 5V operation
Small Die
Controlled rise and fall times and output slew rate
Provides flexibility in output configurations and testing
Enables low-power operation or output enable function
Provides flexibility for system applications, through selectable
instantaneous or synchronous change in outputs
Suitable for most PC, consumer, and networking applications
Lowers inventory cost as same die services both applications
Enables encapsulation in small-size, surface mount packages
Has lower EMI than oscillators
