    • Central Clock Generator for DLP™ Systems

The CDCDLP223 is a PLL-based high performance clock synthesizer that is optimized for use in DLP™ systems. It uses a 20 MHz crystal to generate the fundamental frequency and derives the frequencies for the 100 MHz HCLK and the 300 MHz HCLK output. Further, the CDCDLP223 generates a buffered copy of the 20 MHz Crystal Oscillator Frequency at the 20 MHz output terminal.

The 100 MHz HCLK output provides the reference clock for the XDR Clock Generator (CDCD5704). Spread-spectrum clocking with 0.5% down spread, which reduces Electro Magnetic Interference (EMI), is applied in the default configuration. The spread-spectrum clocking (SSC) is turned on and off via the serial control interface.

The 300 MHz HCLK output provides a 200-400 MHz clock signal for the DMD Control Logic of the DLP™ Control ASIC. Frequency selection in 20 MHz steps is possible via the serial control interface. Spread-spectrum clocking with ±1.0% or ±1.5% center spread is applied, which can be disabled via the serial control interface

The CDCDLP223 features a fail safe start-up circuit, which enables the PLLs only if a sufficient supply voltage is applied and a stable oscillation is delivered from the crystal oscillator. After the crystal start-up time and the PLL stabilization time, all outputs are ready for use.

The CDCDLP223 works from a single 3.3-V supply and is characterized for operation from -40°C to 85°C.
