The PL611s-02 accepts a fundamental input crystal of 10MHz to 50MHz or reference clock input of 1MHz to 200MHz and is capable of producing two outputs up to 200MHz. This flexible design allows the PL611s-02 to deliver any PLL generated frequency, F REF (Crystal or Ref Clk) frequency or F REF /(2*P) to CLK0 and/or CLK1. Some of the design features of the PL611s-02 are mentioned below: PLL Programming Output Enable (OE) The PLL in the PL611s-02 is fully programmable. The PLL is equipped with an 8-bit input frequency divider (R-Counter), and an 11-bit VCO frequency feedback loop divider (M-Counter). The output of the PLL is transferred to a 5-bit post VCO divider (PCounter). The output frequency is determined by the following formula [F OUT = F REF * M / (R * P) ]. The Output Enable feature allows the user to enable and disable the clock output(s) by toggling the OE pin. The OE pin incorporates a 60kΩ pull up resistor giving a default condition of logic “1”. Clock Output (CLK0) CLK0 is the main clock output. The output of CLK0 can be configured as the PLL output (F VCO /(2*P)), F REF (Crystal or Ref Clk) output, or F REF /(2*P) output. The output drive level can be programmed to Low Drive (4mA), Standard Drive (8mA) or High Drive (16mA). The maximum output frequency is determined by the Power Supply Voltage; 200MHz at 3.3V, 166MHz at 2.5V and 133MHz at 1.8V. Clock Output (CLK1) The CLK1 feature allows the PL611s-02 to have an additional clock output programmed to one of the following: Power-Down Control (PDB) The Power Down (PDB) feature allows the user to put the PL611s-02 into “Sleep Mode”. When activated (logic ‘0’), PDB ‘Disables the PLL, the oscillator circuitry, counters, and all other active circuitry. In Power Down mode the IC consumes <10µA of power. The PDB pin incorporates a 60kΩ pull up resistor giving a default condition of logic “1”. Frequency Select (FSEL) The Frequency Select (FSEL) feature allows the PL611s-02 to switch between two pre-programmed outputs allowing the device “On the Fly” frequency switching. The FSEL pin incorporates a 60kΩ pull up resistor giving a default condition of logic “1”.

It is not recommended to place this component on the backside of the PCB. Going through vias will reduce the signal integrity, causing additional jitter and phase noise. - It is highly recommended to keep the VDD and GND traces as short as possible. - When connecting long traces (> 1 inch) to a CMOS output, it is important to design the traces as a transmission line or ‘stripline’, to avoid reflections or ringing. In this case, the CMOS output needs to be matched to the trace impedance. Usually ‘striplines’ are designed for 50Ω impedance and CMOS outputs usually have lower than 50 Ω impedance so matching can be achieved by adding a resistor in series with the CMOS output pin to the ‘stripline’ trace. - Please contact PhaseLink for additional information on how to design outputs driving long traces or for the Gerber files for the PL611s-02 eval board shown.
