NBC12429AFNG Datasheet PDF - ON Semiconductor

The NBC12429 and NBC12429A are general purpose, PLL based synthesized clock sources. The VCO will operate over a frequency range of 200 MHz to 400 MHz. The VCO frequency is sent to the N-output divider, where it can be configured to provide division ratios of 1, 2, 4, or 8. The VCO and output frequency can be programmed using the parallel or serial interfaces to the configuration logic. Output frequency steps of 1.0 MHz can be achieved using a 16 MHz crystal, depending on the output dividers. The PLL loop filter is fully integrated and does not require any external components. The NBC12429 is specified to operate across the commercial temperature range. The NBC12429A is specified to operate across the industrial temperature range.
