Products Detail

The CDCE421 is a high-performance, low-phase-noise clock generator. It has two fully integrated, low-noise, LC-based voltage controlled oscillators (VCOs) that operate in the 1.750-GHz to 2.350-GHz frequency range. It has an integrated crystal oscillator that operates in conjunction with an external AT-cut crystal to produce a stable frequency reference for the PLL-based frequency synthesizer. The CDCE421 supports one differential LVDS clock output or one differential LVPECL output. All device settings are programmable through a Texas Instruments proprietary simple serial interface. The device operates in a 3.3-V supply environment and is characterized for operation from –40°C to +85°C. The CDCE421 is available in a QFN-24 package.
