Description

Vectron's FX-101 is a crystal based frequency tra n s l a t o r which is used to translate any input frequency such as 8 kHz, 1.544 MHz, 2.048 MHz, 19.440 MHz etc.to any spe- cific frequency less than or equal to 77.76 MHz. 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-101 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 8 kHz and 170 MHz t ranslating them to an output frequency up to 77.76 MHz. The "Input Frequency tra cking capability" is the total amount of input frequency deviation in which the FX-101 is guaranteed to tra ck or tra n s l a t e. As an ex a m p l e, a typ- ical input clock would be 8 kHz ±20 ppm.The FX-101 is g u a ranteed to tra ck at least ±50 ppm of error over tem- p e ra t u r e / a g i n g / p ower 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 ex t e rnal circuitry (analog comparators or an A/D conve rter plus a processor) to detect when the con- trol voltage is getting close to the limits of the pull ra n g e.

Input Frequency - The FX-101 series AC couples the input, this means the unit is capable of handling HCMOS, LvHCMOS, PECL and LvPECL input signals. (For Input Frequencies below 1 MHz only HCMOS and LvHCMOS are supported.) GND Ground LD Lock Detect (output) Logic “1” indicates a locked condition Logic “0” indicates that no input signal is present or the input signal has moved out of the lock range. Monitor PLL/ VCXO control voltage (Output) Under locked conditions, should be >0.3V and <3.0V for the 3.3 volt option or >0.5V and <4.5V for the 5 volt option. Input frequency may be out of range if voltage exceeds these limits. --- Missing NC No Connection GND Ground Tri-state HCMOS Logic "1" (or no connect) = Output enabled Logic "0" = Output in high impedance Enable Disable PECL Logic "1" = Output disabled Logic "0" (or no connect) = Output enabled Out Output (PECL) or HCMOS COut Complementary Output (PECL) or GND for HCMOS output option NC No Connection Select A Do not Exceed Vcc Select B Do not Exceed Vcc NC No Connection GND Ground Vcc Power Supply Voltage (5 Vdc or 3.3Vdc) Outline Drawing FX-101 Frequency Translator Vectron International • 267 Lowell Road, Hudson, NH 03051 • Tel: 1-88-VECTRON-1 • Web: www.vectron.com Pin Out

NO CLEAN is the rec- ommended procedure. The FX-100 series has been designed for pick and place reflow soldering. The suggested reflow pro- file 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 tape- n-reel. Handling Precautions Although protection circuitry has been designed into this d ev i c e, proper precautions should be taken to avo i d exposure to electrostatic discharge (ESD) during han- dling and mounting. VI employs a human-body model (HBM) for ESD-susceptibility testing and protection design eva l u a t i o n . ESD voltage thresholds are dependent on the circuit p a rameters used to define the mode. The HBM ESD threshold presented here was obtained by using para- meters where resistance = 1500 ohms, capacitance = 100pf) ESD Threshold Voltage Model Threshold Unit Human Body (HBM) 500 V min

FX-101 Frequency Translator Vectron International • 267 Lowell Road, Hudson, NH 03051 • Tel: 1-88-VECTRON-1 • Web:www.vectron.com FAQ’s Q: What are the different input frequencies that are available? 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 and 10.) Q: How many different input frequencies can a specific FX-101 accept? A: Each FX-101 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-101. (See The Typical Application illustrated on page 6.) Q: Can a single FX-101 handle an application for 4 input frequencies of 8 kHz, 19.44, 38.88 and 77.76 MHz all being translated to 77.76 MHz, with the 77.76 MHz input being LvPECL and the others HCMOS? A: Yes; since the FX-101 AC couples the input signal, this combination can be supported. Q: What is the lock time for the FX-101? 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-101-DFC-A2S2 with 19.44 and 155.52 MHz for the input frequencies and was given a Source Control Drawing (SCD) number of FX-101-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-101 series meets? A: The FX-101 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: Does the output frequency need to be 77.76 MHz? A: No, the output frequency can be any frequency between 1.544 MHz and 77.76 MHz. (A list of standard frequencies is available on pages 9 and 10.) Q: What type of noise on the supply line can the FX-101 suppress? A: The FX-101 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 supply vendor on the best way to filter noise on your supply line.
