This series can accept any input frequency from 10 MHz to 700 MHz and then cleans upup the signal to provide an ultra low jitter output signal. The output jitter of this unit is well below the requirements of OC-192. The CS-300 also has the ability to translate either one or two different input frequencies between 10 MHz and 700 MHz to one common output frequency, such as input frequencies of 622.08 MHz and 666.5143 MHz translated to an output frequency of 622.08 MHz. This unit is of particular interest to those working with FEC applications or needing to switch between 10G and OC-192. The "Input Frequency Tracking Capability" is the total amount of frequency deviation on the input signal that the CS-300 is guaranteed to track. As an example, a typical input clock would be 622.08 MHz ± 20 ppm. The CS-300 is guaranteed to track at least ±40 ppm of error over temperature/ aging/ power supply and is more than twice what most applications require.

NO CLEAN is the recommended procedure. The CS-300 has been designed for pick and place reflow soldering. The suggested reflow profile is shown above. The CS-300 may be reflowed once, and should not be reflowed in the inverted position. The Standard ship method for volume production of the CS-300 series is in a matrix tray. 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. 12 15/16 0.235 0.255deep VI - Logo 0.235 This Cell only CS-300-DFC-P2XXP2 622.08 MHz in 622.08 MHz out 0.125 CS-300-DFC-P2XXP2 622.08 MHz in 622.08 MHz out 0.125 1.05 CS-300-DFC-P2XXP2 622.08 MHz in 622.08 MHz out CS-300-DFC-P2XXP2 622.08 MHz in 622.08 MHz out 4.00 0.125 0.16 0.85 3 x 12 Array / 36 units per tray 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) and a charged-device model (CDM) for ESD-susceptibility testing and protection design evaluation. ESD voltage thresholds are dependent on the circuit parameters used to define the mode. Pin 1 This Corner Although no industry-wide standard has been adopted f or the CDM, a standard HBM (resistance = 1500 ohms, capacitance = 100pf) is widely used and therefore can be used for comparison purposes. The HBM ESD threshold presented here was obtained by using these circuit parameters.

Jumper Sockets 3 Places Enable / Disable Frequency Select A & B FAQs Q1: What are the different input frequencies available? A: The CS-300 is able to handle any input frequency between 10 MHz and 700 MHz. (A list of standard frequencies is available on page 8.) Q2: How many different input frequencies can a specific CS-300 accept? A: Each CS-300 can be programmed to accept up to 2 different input frequencies. Q3: If there is only one set of input pins, how can your unit accept 2 different frequencies? A: The customer is required to supply a multiplexer which would switch between the different input frequencies. The multiplexersselect pin would need to be syncd to the select pin of the CS-300. Q4: What is the lock time for the CS-300? 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. Q5: What type of noise on the supply line can the CS-300 suppress? A: The CS-300 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 of your supply line. 10.000 MHz C4 38.8800 MHz H5 139.264 MHz L5 669.1281 MHz R2 M2 12.800 MHz D2 44.4343 MHz J2 155.520 MHz 13.000 MHz D3 44.7360 MHz J3 156.250 MHz M3 669.3266 MHz 669.6428 MHz R3 R1 15.000 MHz D4 M4 672.1627 MHz R5 D5 J4 J5 161.1328 MHz 16.384 MHz 51.8400 MHz 61.4400 MHz 166.6286 MHz M5 19.440 MHz D6 65.5360 MHz J6 167.3316 MHz N2 20.0000 MHz E2 74.1250 MHz K1 168.0407 MHz N3 690.5692 MHz 693.4830 MHz 710.9486 MHz R4 R6 T2 20.1416 MHz 20.4800 MHz E3 E4 74.2500 MHz K7 311.0400 MHz P1 719.7344 MHz T3 77.7600 MHz K2 T4 E5 78.1250 MHz K3 P2 P6 777.6000 MHz 22.2171 MHz 622.0800 MHz 624.7048 MHz 26.0000 MHz F3 78.6432 MHz K5 625.0000 MHz P3 27.0000 MHz F4 82.9440 MHz K6 627.3296 MHz P7 29.4912 MHz 32.7680 MHz F5 H3 112.000 MHz L2 644.5313 MHz P4 No Second Input Freq XX 114.000 MHz L3 666.5143 MHz P5 Input Freq not listed SS 37.0560 MHz H4 125.000 MHz L4 Output Freq not listed SS CS - 300 - D F C - P2 Supply Voltage C = 5 Vdc +/-5% D = 3.3 Vdc +/-5% Output Type F = Comp.
