Transcription

1 Crystal Oscillator Module ICs OVERVIEW The 553 series are miniature crystal oscillator module ICs supported 8MHz to 17MHz fundamental oscillation mode. The Oscillator circuit stage has voltage regulator drive, significantly reducing current consumption and crystal current, compared with existing devices, and significantly reducing the oscillator characteristics supply voltage dependency. There are 3 pad layout package options available for optimized mounting, making these devices ideal for miniature crystal oscillators.

6 FUNCTIONAL DESCRIPTION Function output is stopped and becomes high impedance. Oscillator HIGH(Open) f OUT Operating LOW Hi-Z Stopped Power Saving Pull-up Resistor The pin pull-up resistance changes its value to R PU1 or R PU2 in response to the input level (HIGH or LOW). When is tied to LOW level, the pull-up resistance becomes large (R PU1 ), thus reducing the current consumed by the resistance. When is left open circuit or tied to HIGH level, the pull-up resistance becomes small (R PU2 ), thus internal circuit of becomes HIGH level. Consequently, the IC is less susceptible to the effects of noise, helping to avoid problems such as the output stopping suddenly. Oscillation Detection Function The 553 series incorporate an oscillation detection circuit. The oscillation detection circuit disables the output until the oscillator circuit starts up. This function avoids the problem where the oscillator does not start, due to abnormal oscillation conditions, where power is applied or when the oscillator is restarted using. C cancellation circuit Oscillation circuit with a built-in C cancellation circuit provides a fixed compensation amount to cancel the effect of the crystal C. It reduces the C parameter in the equivalent circuit, reducing the shallow negative resistance for increasing values of C. This cancellation circuit makes it easier to maintain the oscillation margin. SEIKO NPC CORPORATION - 6
