1 DATASHEET MK3721 Description The MK3721 series of devices includes the original MK3721S and the new MK3721D. The MK3721D is a drop-in replacement for the MK3721S device. Compared to the earlier device, the MK3721D offers a wider operating frequency range and improved power supply noise rejection. The MK3721 is a low cost, low-jitter, high-performance 3.3 volt designed to replace expensive discrete s modules. The on-chip Voltage Controlled Crystal Oscillator accepts a 0 to 3.3 V input voltage to cause the output clocks to vary by ±100 ppm. Using ICS patented techniques, the device uses an inexpensive external pullable crystal in the range of 16.2 to 28 MHz to produce a output clock at that same frequency. ICS manufactures the largest variety of Set-Top Box and multimedia clock synthesizers for all applications. If more clock outputs are needed, see the MK3732 or MK377x family of parts. Consult ICS to eliminate s, crystals, and oscillators from your board. The frequency of the on-chip is adjusted by an external control voltage input into pin VIN. Because VIN is a high-impedance input, it can be driven directly from an PWM RC integrator circuit. Frequency output increases with VIN voltage input. The usable range of VIN is 0 to 3.3 V. Features MK3721D is a drop-in replacement for the earlier MK3721S device Packaged in 8-pin SOIC Operational frequency range of 16.2 MHz to 28 MHz Uses an inexpensive external crystal On-chip patented with pull range of 200 ppm (minimum) tuning voltage of 0 to 3.3 V Operating voltage of 3.3 V 12 ma output drive capability at TTL levels Advanced, low-power, sub-micron CMOS process For frequencies between 1 MHz and 8 MHz, use the MK3713D. For higher than 28 MHz, use the MK Available in a lead-free package MK3721D is recommended for new designs.

3 External Component Selection The MK3721 requires a minimum number of external components for proper operation. Decoupling Capacitors A decoupling capacitor of 0.01µF should be connected between VDD and GND on pins 2 and 4 as close to the MK3721 as possible. For optimum device performance, the decoupling capacitor should be mounted on the component side of the PCB. Avoid the use of vias in the decoupling circuit. Series Termination Resistor When the PCB trace between the clock output and the load is over 1 inch, series termination should be used. To series terminate a 50Ω trace (a commonly used trace impedance), place a 33Ω resistor in series with the clock line, as close to the clock output pin as possible. The nominal impedance of the clock output is 20Ω. as possible and should be on the same side of the PCB as the MK3721. There should be no via s between the crystal pins and the X1 and X2 device pins. There should be no signal traces underneath or close to the crystal. See application note MAN05. Crystal Tuning Load Capacitors The crystal traces should include pads for small fixed capacitors, one between X1 and ground, and another between X2 and ground. Stuffing of these capacitors on the PCB is optional. The need for these capacitors is determined at system prototype evaluation, and is influenced by the particular crystal used (manufacture and frequency) and by PCB layout. The typical required capacitor value is 1 to 4 pf. The procedure for determining the value of these capacitors can be found in application note MAN05. Quartz Crystal The MK3721 function consists of the external crystal and the integrated oscillator circuit. To assure the best system performance (frequency pull range) and reliability, a crystal device with the recommended parameters (shown below) must be used, and the layout guidelines discussed in the following section shown must be followed. The oscillation frequency of a quartz crystal is determined by its cut and by the load capacitors connected to it. The MK3721 incorporates on-chip variable load capacitors that pull (change) the frequency of the crystal. The crystal specified for use with the MK3721 is designed to have zero frequency error when the total of on-chip + stray capacitance is 14 pf. Recommended Crystal Parameters: Initial Accuracy at 25 C Temperature Stability Aging Load Capacitance Shunt Capacitance, C0 C0/C1 Ratio Equivalent Series Resistance ±20 ppm ±30 ppm ±20 ppm 14 pf 7 pf Max 250 Max 35 Ω Max The external crystal must be connected as close to the chip IDT / ICS 3 MK3721 REV E
4 Absolute Maximum Ratings Stresses above the ratings listed below can cause permanent damage to the MK3721. These ratings, which are standard values for ICS commercially rated parts, are stress ratings only. Functional operation of the device at these or any other conditions above those indicated in the operational sections of the specifications is not implied.
