The PL611s-08 accepts a fundamental input crystal of 10MHz to 50MHz or reference clock input of 1MHz to 100MHz and is capable of producing two outputs up to 75MHz. This flexible design allows the PL611s-08 to deliver any PLL generated frequency, F REF ( Crystal or Ref Clk) frequency or F REF /2 to CLK0 and/or CLK1. Some of the design features of the PL611s-08 are mentioned below: P LL Programming T he PLL in the PL611s-08 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) ]. C lock Output (CLK0) C LK0 is the main clock output. The PL611s-08 can also be programmed to provide a second clock output, CLK1, on the programmable I/O pin (see OE /CLK1 pin description below). The output of CLK0 can be configured as the PLL output (F VCO /(2*P)), F REF ( Crystal or Ref Clk Frequency) output, or F REF /2 output. The output drive level can be programmed to Low Drive (4mA), Standard Drive (8mA) or High Drive (16mA). The maximum output frequency is 75MHz. P rogrammable I/O (OE/CLK1) T he PL611s-08 provides one programmable I/O pin which can be configured as one of the following functions: Output Enable (OE) 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 60k pull up resistor giving a default condition of logic “1”. Clock Output (CLK1) T he CLK1 feature allows the PL611s-08 to have an additional clock output. This output can be programmed to one of the following: FREF - Reference ( Crystal or Ref Clk ) Frequency FREF / 2 CLK0 CLK0 / 2 4 7745 Fremont Blvd., Fremont, California 94538 Tel (510) 492-0990 Fax (510) 492-0991 w ww.phaselink.com R ev 12/12/06 Page 3 ( Preliminary) PL611s-08 L ow-Power Programmable Quick Turn Clock T M E LECTRICAL SPECIFICATIONS ABSOLUTE MAXIMUM RATINGS P ARAMETERS S upply Voltage Range I nput Voltage Range O utput Voltage Range S oldering Temperature (Green package) D ata Retention @ 85 ° C S torage Temperature A mbient Operating Temperature* SYMBOL V DD VI VO MIN.

In this case, the CMOS output needs to be matched to the trace impedance. Usually ‘striplines’ are designed for 50 impedance and CMOS outputs usually have lower than 50 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 additional application assistance.
