Vaishali Semiconductor VT83201
VT83201 is a single-chip, integrated VCXO and Phase Locked Loop (PLL) clock synthesizer. The device uses the VCXO and an analog Phase-Locked Loop (PLL) to accept a 10 MHz to 20 MHz, 30pF (pull range of 200 ppm) crystal input, in order to produce either one or two output clocks.| Part No. | VT83201 |
