General Description

The Vaishali VT83205 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 14.318 MHz, 30pF (pull range of 200 ppm) crystal input, in order to produce either one or two output clocks. A 0 to 3V control signal is used to fine tune the output clock frequency in the ±100ppm range. Select inputs SO:S2 are used for frequency and output selection.

Features

• 3.3V supply operation

• Packaged in 16-pin SOIC & QSOP packages.

• Replaces separate VCXO and multiplier

• Uses inexpensive pullable crystal

• On-chip VCXO with 200 ppm pull range (±100

ppm)

• 5V-tolerant control inputs

• Zero ppm synthesis error in both clocks

Applications

• Telecom switching

• Set-top boxes

• HDTV

• MPEG Video clock source
