The input frequency does not have to be a 50/50% duty cycle and as an example can be an 8 kHz signal with a logic high "on time" of only 1us, such as a BITS clock. The FX-104 also has the ability to translate any of 1 to 4 different input frequencies to one common output frequency, such as input frequencies of 8 kHz and 1.544 MHz and 19.44 MHz and any other frequency between 333 Hz and 170 MHz translating them to any specific output frequency from 170 MHz to 777.600 MHz. The "Input Frequency tracking capability" is the total amount of input frequency deviation in which the FX104 is guaranteed to track or translate. As an example, a typical input clock would be 8 kHz ±20 ppm. The FX104 is guaranteed to track at least ±40 ppm of error over temperature/ aging/ power supply and is more than twice what most applications require. The PLL control voltage is brought out through a 470K ohm resistor. This would allow for the use of external circuitry (analog comparators or an A/D converter plus a processor) to detect when the control voltage is getting close to the limits of the pull range.

NO CLEAN is the recommended procedure. The FX-100 series has been designed for pick and place reflow soldering. The suggested reflow profile is shown above. The FX-100 series may be reflowed once, and should not be reflowed in the inverted position.

These trays are 100% recyclable. The trays also offer the added feature that they can be continuously feed into a pick-n-place machine eliminating the down time required with tapen-reel. Handling Precautions Although protection circuitry has been designed into this device, proper precautions should be taken to avoid exposure to electrostatic discharge (ESD) during handling and mounting. VI employs a human-body model (HBM) for ESD-susceptibility testing and protection design evaluation. ESD voltage thresholds are dependent on the circuit parameters used to define the mode. The HBM ESD threshold presented here was obtained by using parameters where resistance = 1500 ohms, capacitance = 100pf) ESD Threshold Voltage Model Human Body (HBM) Threshold Unit 500 V min Vectron International • 267 Lowell Road, Hudson, NH 03051 • Tel: 1-88-VECTRON-1 • Web: www.vectron.com FX-104 Frequency Translator Typical Application All components outside the dotted line box are user supplied components.

A: The FX-100 series is able to handle any input frequency between 8 kHz and 170 MHz. (A list of standard frequencies is available on pages 9 & 10) Q: How many different input frequencies can a specific FX-104 accept? A: Each FX-104 can be programmed to accept up to 4 different frequencies. Q: If there is only one input pin, how can your unit accept 4 different frequencies? A: The user is required to supply a multiplexer which would switch between the different input frequencies.The multiplexers’ select pins would need to be sync’d to the select pins of the FX-104. (See The Typical Application illustrated on page 6) Q: Can a single FX-104 handle an application for 4 input frequencies of 8 kHz, 19.44, 77.76 and 155.52 MHz all being translated to 622.08 MHz, with the 155.52 MHz input being LvPECL and the others HCMOS? A: Yes; since the FX-104 AC couples the input signal, this combination can be supported. Q: What is the lock time for the FX-104? A: The exact lock time will depend on the specific input frequency. It should be noted that in all cases the lock time will be significantly less than 1 second. Q: I asked for a FX-104-DFC-A2S8 with 19.44 and 155.52 MHz for the input frequencies and was given a Source Control Drawing (SCD) number of FX-104-DFC-S5999. Why was a new number assigned? A: Whenever there are multiple input frequencies, we need to assign a SCD for the unit so that we can include a table indicating what the logic levels need to be on pins 12 and 13 to control the unit per the correct input frequency. Q: What are the exact jitter transfer specs that the FX-104 series meets? A: The FX-104 meets the stringent jitter transfer specs in GR-253 for Category II jitter (Section 5.6.2.1.2) for all OC-n levels. Q: My circuit card is already laid out for the FX-102, Is the FX-104 footprint compatible? A: Yes;The FX-104 package is a drop in replacement for the FX-102 package. The only difference is in the logic level for the Output Disable/Enable pin.They are opposite between the FX-102 and FX-104. However letting pin 8 float will allow both units to be enabled. Q: What type of noise on the supply line can the FX-104 suppress? A: The FX-104 is designed to clean up noise on the Input Clock Signal, it is not designed to clean up noisy power supplies. If excessive noise is present on the supply line it may degrade the output jitter performance. Additional external filtering may be required. Please consult with your power suppl y vendor on the best way to filter noise on your supply line.
