Designed for low-power applications with very stringent space requirement, PL611s-28 consumes about 1.2mA, while producing 2 distinct outputs of 27MHz and 13.5MHz. Designed to fit in a small SOT, SC70, or SOT23 package for high performance applications, the PL611s-28 offers excellent phase noise and jitter performance. The power down feature of PL611s-28, when activated, allows the IC to consume less than 5 A of power, while its programming flexibility allows generating any output, using a low-cost crystal or reference input. In addition, one programmable I/O pin can be configured as Output Enable (OE), Frequency switching (FSEL), Power Down (PDB) input, or CLK1 (F OUT , F REF , F REF /2) output.

The PL611s-28 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 125MHz. This flexible design allows the PL611s-28 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-28 are mentioned below: P LL Programming T he PLL in the PL611s-28 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 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*P) output. Clock Output (CLK1) T he CLK1 feature allows the PL611s-28 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 The output drive level can be programmed to Low Drive (4mA), Standard Drive (8mA) or High Drive (16mA) for each clock independently. The maximum output frequency is 125MHz. Output Enable (OE) T he 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”. The OE feature can be programmed to allow the output to float (Hi Z), or to operate in the ‘Active low’ mode. Power-Down Control (PDB) T he Power Down (PDB) feature allows the user to put the PL611s-28 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 50MHz.
