DATASHEET PLL AUDIO CLOCK SYNTHESIZER MK2703B IDT™ / ICS™ PLL AUDIO CLOCK SYNTHESIZER 1 MK2703B REV D 042606 Description The MK2703B is a low-cost, low-jitter, high performance PLL clock synthesizer designed to replace oscillators and PLL circuits in set-top box and multimedia systems. Using ICS’ patented analog Phase Locked Loop (PLL) techniques, the device uses a 27 MHz crystal or clock input to produce a buffered reference clock and a selectable audio clock. ICS manufactures the largest variety of Set-Top Box and multimedia clock synthesizers for all applications. Consult ICS to eliminate VCXOs, crystals and oscillators from your board. Features • Packaged in 8-pin SOIC • Available in RoHS compliant package • Uses an inexpensive, fundamental mode crystal or clock • Patented zero ppm synthesis error in all clocks • All frequencies are frequency locked • Advanced, low power, sub-micron CMOS process • Operating voltage of 3.3 V or 5 V • Industrial temperature version available Block Diagram Audio Clock PLL Clock Synthesis and Control Circuitry 27 MHz crystal or clock input VDD Crystal Oscillator S1:0 X1 X2 27M GND 2 Capacitors are required for crystal tuning

A decoupling capacitor of 0.01µF must be connected between VDD and GND on pins 2 and 3. It must be connected close to the MK2703B to minimize lead inductance. No external power supply filtering is required for the MK2703B. Series Termination Resistor A 33Ω terminating resistor can be used next to the clock outputs for trace lengths over one inch. Crystal Load Capacitors The total on-chip capacitance is approximately 16 pF. A parallel resonant, fundamental mode, AT cut 27 MHz crystal should be used. The device crystal connections should include pads for small capacitors from X1 to ground and from X2 to ground.

Because load capacitance can only be increased in this trimming process, it is important to keep stray capacitance to a minimum by using very short PCB traces (and no vias) between the crystal and device. Crystal capacitors, if needed, must be connected from each of the pins X1 and X2 to ground. The value (in pF) of these crystal caps should equal (CL -16 pF)*2. In this equation, CL= crystal load capacitance in pF. Example: For a crystal with an 18 pF load capacitance, each crystal capacitor would be 4 pF [(18-16) x 2] = 4. Absolute Maximum Ratings Stresses above the ratings listed below can cause permanent damage to the MK2703B. 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. Exposure to absolute maximum rating conditions for extended periods can affect product reliability. Electrical parameters are guaranteed only over the recommended operating temperature range.
