The 307-03 is a dynamic, serially programmable clock source which is flexible and takes up minimal board space. Output frequencies are programmed via a 3-wire SPI port. An advanced PLL coupled to an array of configurable output dividers and three outputs allows low-jitter generation of frequencies from 200 Hz to 270 MHz. The device can be reprogrammed during operation, making it ideal for applications where many different frequencies are required, or where the output frequency must be determined at run time. Glitch-free frequency transitions, where the clock period changes slightly over many cycles, are possible.

The 308 is a versatile serially programmable, quad PLL clock source. The 308 can generate any frequency from 250 kHz to 200 MHz, and up to 6 different output frequencies simultaneously. The outputs can be reprogrammed on the fly, and will lock to a new frequency in 10 ms or less. Smooth transitions (in which the clock duty cycle remains roughly 50%) are guaranteed if the output divider is not changed. The device includes a PDTS pin which tri-states the output clocks and powers down the entire chip. The 308 default for non-programmed start-up are buffered reference clock outputs on all clock output pins.

The 309 is a versatile serially-programmable, triple PLL with spread spectrum clock source. The 309 can generate any frequency from 250kHz to 200 MHz, and up to 6 different output frequencies simultaneously. The outputs can be reprogrammed on-the-fly, and will lock to a new frequency in 10 ms or less. To reduce system EMI emissions, spread spectrum is available that supports modulation frequencies of 31 kHz and 120 kHz, as well as modulation amplitudes of +/-0.25% to +/-2.0%. Both center and down-spread options are available. The device includes a PDTS pin which tri-states the output clocks and powers down the entire chip. The 309 default for non-programmed start-up are buffered reference clock outputs on all clock output pins. IDT's VersaClockTM programming software allows the user to configure up to 9 outputs with target frequencies, spread spectrum capabilities or buffered reference clock outputs. The VersaClockTM software automatically configures the PLLs for optimal overall performance.

The 342 is a low cost, dual-output, field programmable clock synthesizer. The 342 can generate two output frequencies from 250 kHz to 200 MHz, using up to two independently configurable PLLs. The outputs may employ Spread Spectrum techniques to reduce system electro-magnetic interference (EMI). Using ICS' VersaClockTM software to configure the PLL and output, the 342 contains a One-Time Programmable (OTP) ROM to allow field programmability. Programming features include 2 selectable configuration registers. Using Phase-Locked Loop (PLL) techniques, the device runs from a standard fundamental mode, inexpensive crystal, or clock. It can replace multiple crystals and oscillators, saving board space and cost. The device also has a power down feature that tri-states the clock outputs and turns off the PLLs when the PDTS pin is taken low. The 342 is also available in factory programmed custom versions for high-volume applications.

The 343 is a low cost, triple-output, field programmable clock synthesizer. The 343 can generate three output frequencies from 250 kHz to 200 MHz, using up to three independently configurable PLLs. The outputs may employ Spread Spectrum techniques to reduce system electro-magnetic interference (EMI). Using IDT's VersaClock™ software to configure the PLL and output, the 343 contains a One-Time Programmable (OTP) ROM to allow field programmability. Using Phase-Locked Loop (PLL) techniques, the device runs from a standard fundamental mode, inexpensive crystal, or clock. It can replace multiple crystals and oscillators, saving board space and cost. The device also has a power down feature that tri-states the clock outputs and turns off the PLLs when the PDTS pin is taken low. The 343 is also available in factory-programmed custom versions for high-volume applications.

The 345 field programmable clock synthesizer generates up to nine high-quality, high-frequency clock outputs including multiple reference clocks from a low-frequency crystal or clock input. It is designed to replace crystals and crystal oscillators in most electronic systems. Using IDT's VersaClockTM software to configure PLLs and outputs, the 345 contains a One-Time Programmable (OTP) ROM to allow field programmability. Programming features include eight selectable configuration registers, up to two sets of four low-skew outputs, and optional Spread Spectrum outputs. Using Phase-Locked Loop (PLL) techniques, the device runs from a standard fundamental mode, inexpensive crystal, or clock. It can replace multiple crystals and oscillators, saving board space and cost. The 345 is also available in factory programmed custom versions for high-volume applications.

The 495-25-141 is a ceramic, seam-sealed, SMD, crystal for use with Renesas' VCXO-based synchronization PLLs.
