DS4077L-DC0

Rev 3; 9/06 50MHz to 122.88MHz VCXO The DS4077 is an integrated voltage-controlled crystal oscillator (VCXO) module designed to provide reference clock generation in base stations, telecom/datacom, and wireless applications. The DS4077 is developed using a fundamental quartz crystal plus a unique integrated circuit design. The internal fundamental quartz crystal determines the frequency of operation. Custom frequencies are available. Contact the factory for availability. The DS4077 is designed for use with applications requiring low phase noise and jitter. Jitter performance of better than 0.8ps RMS is achieved over the 12kHz to 20MHz range. Phase noise performance of better than -125dBc/Hz at 1kHz is achieved with this design. Applications Features ♦ 50MHz to 122.88MHz Frequency ♦ 3.135V to 3.465V Operation ♦ Low Jitter: < 0.8ps RMS ♦ ±69ppm Absolute Pull Range (APR) ♦ Output Options: LVCMOS Output Buffer LVDS Complementary Output Buffer ♦ Minimum ±110ppm Tuning Range (+25°C) ♦ 14mm x 9mm x 3.06mm Plastic LGA Package Clock-Data Recovery in Telecom/Datacom Applications Data Retiming Reference Clock Generation in Base Stations and Wireless Applications Ordering Information PART TEMP RANGE OUTPUT TYPE FREQUENCY (fNOM) (MHz) PIN-PACKAGE TOP MARK DS4077L-DCN -40°C to +85°C LVCMOS 54 9 LGA DS4077L-DCN DS4077L-DDN -40°C to +85°C LVDS 54 9 LGA DS4077L-DDN DS4077L-CCN -40°C to +85°C LVCMOS 61.44 9 LGA DS4077L-CCN DS4077L-CDN -40°C to +85°C LVDS 61.44 9 LGA DS4077L-CDN Ordering Information continued at end of data sheet.
