ADVANCE INFORMATION
PI6CX100-271
27 MHz 3.3V VCXO for
Set-Top Box Applications
Features
Description
The PI6CX100-271 is a low-cost, high-performance 3.3V VCXO,
designedtoreplaceexpensiveVCXOmodules. Theon-chipVoltage
Controlled Crystal Oscillator accepts a 0 to 3.3V input voltage to
cause clocks to vary by ±120ppm. This device uses an inexpensive
external pullable crystal at 27 MHz to produce the same output
frequency.
• 3.3V operating voltage
• Uses an inexpensive external crystal (PI6X027)
• On-chip VCXO with pull range of 240ppm
• VCXO tuning voltage from 0 to 3.3V
• 10mA output drive at CMOS levels
• Packaging (Pb-free & Green available):
- 8-pin TSSOP (L)
The PI6CX100-271 is designed for Set-Top Box applications.

Maximum Ratings
(Above which the useful life may be impaired. For user guidelines,
not tested.)
Note:
Storage Temperature .........................................–55°C to 125°C
Ambient Temperature ........................................–40°C to 85°C
Stresses greater than those listed under MAXIMUM RATINGS may cause
permanent damage to the device. This is a stress rating only and func-
tional operation of the device at these or any other conditions above those
indicated in the operational sections of this specification is not implied.
Exposure to absolute maximum rating conditions for extended periods
may affect reliability.
