Product Data Sheet FX-500 Low Jitter Frequency Translator Features Description The FX-500 is a complete crystal-based frequency translator used in communications applications where low jitter is paramount. Performance advantages include superior jitter performance, high output frequencies and small package size. Advanced custom ASIC technology results in a highly robust, reliable and predictable device. The device is packaged in a 6 pin J-Lead ceramic package with a hermetic seam welded lid. • Complete Frequency Translator to 77.760 MHz • 3.3 Volt or 5.0 Volt Supply • Capable of locking to an 8 kHz pulse/ BITS clock • Tri-State Output allows board test • Lock Detect • J-Lead Ceramic Package • Advanced Custom ASIC Technology • Absolute Pull Range Performance to ±100 ppm • CMOS Output • Commercial or Industrial Temperature Range • EIA Compatible Tape and Reel Packaging Applications • • • • • Frequency Translation, Clock Smoothing Telecom - SONET/SDH/ATM/DWDM Datacom - DSLAM, DSLAR, Access Nodes Cable Modem Head End Base Station - GSM, CDMA Figure 1.

A 0.1 µF low frequency tantalum bypass capacitor in parallel with a 0.01 µF high frequency ceramic capacitor is recommended. 2. Figure 2 defines the waveform parameters. Figure 3 illustrates the standard test conditions under which these parameters are specified and tested. 3. Duty cycle is defined as (on timeperiod), with VS = VDD/2, per Figure 2. Duty cycle is measured with a 15pf load per Figure 3. 4. Other frequencies may be available, please contact factory. . Figure 2. Output Waveform . Figure 3.

Tristate is driven to logic high or logic low; there is no internal pull up or pull down resistor. 2. LD is an open collector output requiring a 30k ohm pullup resistor to VDD. LD output is logic high under locked condition, logic low for no input at fIN, and for "out-of-lock" condition LD transitions between logic low and logic high at the phase detector frequency.

Functional operation is not implied at these or any other conditions in excess of conditions represented in the operational sections of this data sheet.

VI employs a Human Body Model and a charged device model for ESD-susceptibility testing and design protection evaluation. ESD thresholds are dependent on the circuit parameters used to define the model. Although no industry wide standard has been adopted for the CDM, a standard HBM of resistance = 1500Ω and capacitance = 100pf is widely used and therefore can be used for comparison purposes.
