VCXO Clock Generator
Features
Description
On-chip tunable voltage-controlled crystal oscillator circuitry (VCXO) allows precise system frequency tuning (pull range typically 300ppm) Uses inexpensive fundamental-mode crystals Integrated phase-locked loop (PLL) multiplies VCXO frequency higher system frequencies needed 3.3V supply voltage available Small circuit board footprint: (8-pin 0.150 SOIC) Custom frequency selections available contact your local Sales Representative more information
FS6130 monolithic CMOS clock generator designed minimize cost component count digital video/audio systems. high-resolution phase-locked loop generates three output clocks through array post-dividers. frequencies ratiometrically derived from crystal oscillator frequency. locking output frequencies together eliminate unpredictable artifacts video systems reduce electromagnetic interference (EMI) frequency harmonic stacking.
