CY2VC521-2 Low Noise LVDS Clock Generator with VCXO • Output 216 MHz Output Clock • Input External 27 MHz Crystal • Differential LVDS Output with 2x Drive to Drive Two Loads • VCXO gives 230 ppm Minimum Pull Range • Low RMS Phase Jitter 12 MHz ps Typical • Low Phase Noise • Fully Integrated Low Noise Phase Locked Loop PLL • Excellent Voltage-to-Frequency Linearity • Supply Voltage 3.3V • Pb-free 16-Pin TSSOP Package The CY2VC521-2 is a PLL-based clock generator with VCXO control and very low output jitter. When the user connects a fundamental mode 27 MHz crystal, this device generates a 216 MHz output clock. The CY2VC521-2 has one LVDS output pair tuned to drive two standard LVDS loads and operates from a single 3.3V power supply. The VIN pin is an analog input that enables the user to pull the output frequency. The pullability range is at least 230 ppm ±115 ppm . Unlike conventional VCXO designs, the output frequency adjustment is not achieved by adjusting capacitance at the pins of the crystal. Instead, a proprietary PLL design is used. This permits the use of a standard 27 MHz crystal. A special “pullable” crystal is neither required nore recommended.
