5041 series
High-stability Crystal Oscillator IC with Frequency Adjustment Function
OVERVIEW
The 5041 series are high-stability clock oscillator ICs with built-in frequency adjustment functions. The
frequency adjustment functions can be optimized, by the addition of a minimal adjustment process, to improve
the frequency stability. The function is implemented using frequency adjustment data written to a built-in
EEPROM over a 1-wire serial interface. The ICs are ideal for compact crystal oscillators for use in applications
such as WiMAX (Worldwide Interoperability for Microwave Access) and PLC (Power Line Communication)
that require high frequency stability in the order of ±30 to ±10ppm. They use a pad layout suitable for flip chip
bonding mounting.

• 5041B×A: 1.60V to 2.25V
I Recommended oscillation frequency range:
20MHz to 55MHz (for fundamental oscillation)
I Frequency divider built-in:
• Selectable by version: fO, fO/2, fO/4, fO/8, fO/16,
fO/32
• Frequency divider output for 0.625MHz (min)

*1. The recommended oscillation frequency is a yardstick value derived from the crystal used for NPC characteristics authentication. However, the oscilla-
tion frequency range is not guaranteed. Specifically, the characteristics can vary greatly due to crystal characteristics and mounting conditions, so the
oscillation characteristics of components must be carefully evaluated.

TEMPERATURE ADJUSTMENT FUNCTION GAIN SETTING RATIO
Temperature adjustment function gain setting ratio of 5041A×A and 5041A×B differs. In the case of tempera-
ture adjustment function that rotates temperature characteristics on T0 origin, adjustment sensitivity of
5041A×B is designed twice as higher than that of 5041A×A based on non-compensation temperature deviation
in same register value setting.
