This device is designed to provide input clock smoothing - while providing Phase and Frequency Locked higher frequency translated output. Typical application would take a 10MHz reference frequency and phase and frequency lock it to either a 20MHz or a 40MHz Low Jitter VCXO. The implemented technology significantly attenuates the jitter content of the 10MHz reference signal; while keeping the higher frequency RF Output - Frequency and Phase Coherent with the input 10MHz reference signal. Features: 5*7*2 mm SMT, RoHS Compliant reflow-able package Frequency translation to either 20MHz or 40MHz carrier +3.3V Supply Voltage Industrial operating temperature range (-40C to +85C) LVCMOS Output Internal absolute pull range > 100 ppm allowing for long term drift correction Applications: Frequency translation, clock smoothing and jitter attenuation of the input 10MHz reference Datacom - DSLAM, DSLAR, Access Nodes Cable modem head end Base Station - GSM, CDMA Telecom - SONET/SDH/ATM Block Diagram Mixer 10MHz Reference 20MHz or 40MHz Low Jitter VCXO RF Output Comparator _______________________________________________________________________________________________________ Abracon Corporation (www.abracon.com) Page (1) of (4) 30332 Esperanza Rancho Santa Margarita, CA-92688 Tel: (949) 546-8000 Fax: (949) 546-8001 Tech-Support@abracon.com 1.0 Electrical Specifications: Parameters Reference Input Reference Input Waveform Level "1" (Logic High) Minimum Typical Maximum 10.000 Units MHz 2.00 5.50 Volts Level "0" (Logic Low) 0.80 Volts Rise & Fall Time Duty Cycle Translated Output Standard Available Frequencies Operating Temperature Range Current Drain Supply Voltage (Vdd) 10.0 60 ns % MHz 40 -40 3.135 20.000 20.000 & 40.000 MHz +85 5.0 10.0 3.30 3.465 All Inclusive Frequency Stability of the VCXO VCXO pull range 50.00 100.0 RF Output Waveform Level "1" (Logic High) Level "0" (Logic Low) Load Rise & Fall Time Duty Cycle Lock Time Spectral Content Spurious Response Phase Noise @ 20MHz Carrier (Vdd=3.3V) @ 1,000 Hz offset @ 10,000 Hz offset @ 100,000 Hz offset @ 1,000,000 Hz offset Notes CMOS & TTL Compatible LVCMOS C mA Volts ppm ppm Includes set tolerance, shift through reflow, stability over temperature, load pulling, frequency pushing and 10-years of Aging Sufficient frequency pull is designed-in to provide long-term frequency lock capability LVCMOS 0.9*Vdd 0.1*Vdd 15 45 3.0 -50 3.0 55 5.0 Volts Volts pf ns % ms -70 dBc -134 -150 -154 -155 dBc / Hz dBc / Hz dBc / Hz dBc / Hz _______________________________________________________________________________________________________ Abracon Corporation (www.abracon.com) Page (2) of (4) 30332 Esperanza Rancho Santa Margarita, CA-92688 Tel: (949) 546-8000 Fax: (949) 546-8001 Tech-Support@abracon.com 2.0 Free Running VCXO Phase Noise without Lock @ 19.660916MHz carrier _______________________________________________________________________________________________________ Abracon Corporation (www.abracon.com) Page (3) of (4) 30332 Esperanza Rancho Santa Margarita, CA-92688 Tel: (949) 546-8000 Fax: (949) 546-8001 Tech-Support@abracon.com 3.0 Package Outline 5.0 mm 7.0 mm 4.0 Reel Size: 1k units per reel 5.0 Part Identification ABFT - MHz - T Frequency in MHz 20.000 MHz Or 40.000 MHz _______________________________________________________________________________________________________ Abracon Corporation (www.abracon.com) Page (4) of (4) Mouser Electronics Authorized Distributor Click to View Pricing, Inventory, Delivery & Lifecycle Information: ABRACON: ABFT-20.000MHz-T ABFT-20.000MHz-T2 ABFT-40.000MHz-T ABFT-40.000MHz-T2
