VT98000 Multifrequency Synthesizer
Applications
•= Set-top boxes •= MPEG Video clock source
General Description
The Vaishali VT98000 is a single-chip, integrated multiple Phase Locked Loop (PLL) clock synthesizer. The device uses an analog Phase Locked Loop (PLL) to accept a 27 MHz crystal input to produce multiple outputs. Selection pins are used to provide various outputs.
Features
•= •= •= •= 24.576 MHz for Firewire IEEE1394 or video digitizer 24.576 MHz / 28.224 MHz for software or hardware modem 27 MHz buffered output clock 6.000MHz buffered output clock •= •= •= •= •= 18.432 MHz for audio processor 2kHz standby clock Zero ppm synthesis error in all clocks (except the 2 kHz standby clock) 5V tolerant inputs 20-pin, 150 mil SSOP (QSOP)
