CF5073 series
VCXO Module ICs with Built-in Varicap
OVERVIEW
The CF5073 series are VCXO ICs with built-in varicap diode. They use a recently developed negative-resis-
tance switching oscillation circuit, at oscillation startup and during normal oscillation, for both good oscilla-
tion startup characteristics and wide pullrange. Furthermore, it employs a CMOS process varicap diode, and
also features all the necessary VCXO structure circuit components on a single chip, forming a VCXO module
with just the connection of an external crystal.
FEATURES
I 3.0 to 3.6V supply voltage range
I 10MHz to 60MHz operating frequency
(varies with version)
I Uses negative-resistance switching function
I Varicap diode built-in
I Frequency divider built-in (varies with version: fO,
fO/2, fO/4, fO/8, fO/16, fO/32)
SERIES LINEUP
I CMOS output level
I 50 ± 10% output duty
I 6mA (min) output drive capability
I 15pF output load capacitance CL
I Standby function
(high impedance in standby mode)
I Chip form (CF5073××)

1. The typical oscillation frequency is the oscillation frequency criteria for use when selecting the device version. Note that the oscillation
characteristics and pullability vary with the crystal used and the mounting conditions. Even for the same frequency, the optimal version can vary
with crystal characteristics, so careful evaluation should be exercised when selecting the device version.
2. These versions are produced after receiving a purchase order. Please ask our Sales & Marketing section for further detail.
