The PL610-01 accepts a fundamental input crystal of 5MHz to 130MHz or a reference clock input of 1MHz to 130MHz and is capable of producing two outputs up to 130MHz. This flexible design allows the PL610-01 to deliver any frequency, FREF (Crystal or Ref Clk) frequency, FREF / 2 or FREF / P to CLK0 and/or CLK1. Some of the design features of the PL610-01 are mentioned below: Clock Output (CLK0) Power-Down Control (PDB) CLK0 is the main clock output. The output from CLK0 can be FREF (Crystal or Ref Clk), FREF/2 or FREF/P output. The output drive level can be programmed to Low Drive (4mA), Standard Drive (8mA) or High Drive (16mA). The Power Down (PDB) feature allows the user to put the PL610-01 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 10MΩ pull up resistor giving a default condition of logic “1”. Programmable I/O (OE/PDB/CLK1) The PL610-01provides 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 60kΩ pull up resistor giving a default condition of logic “1”. Clock Output (CLK1) The CLK1 feature allows the PL610-01 to have an additional clock output programmed to one of the following: FREF - Reference (Crystal or Ref Clk) Frequency FREF / 2 CLK0 47745 Fremont Blvd., Fremont, California 94538 Tel (510) 492-0990 Fax (510) 492-0991 www.phaselink.com Rev 4/2/07 Page 3 (Preliminary) PL610-01 1.8V to 3.3V, 1MHz to 130MHz XO IC LAYOUT RECOMMENDATIONS The following guidelines are to assist you with a performance optimized PCB design: Signal Integrity and Termination Considerations Decoupling and Power Supply Considerations - Keep traces short! - Place decoupling capacitors as close as possible to the VDD pin(s) to limit noise from the power supply - Trace = Inductor. With a capacitive load this equals ringing! - Long trace = Transmission Line. Without proper termination this will cause reflections (looks like ringing). - Multiple VDD pins should be decoupled separately for best performance. - Addition of a ferrite bead in series with VDD can help prevent noise from other board sources - Design long traces as “striplines” or “microstrips” with defined impedance. - Match trace at one side to avoid reflections bouncing back and forth. - Value of decoupling capacitor is frequency dependant. Typical values to use are 0.1F for designs using crystals < 50MHz and 0.01F for designs using crystals > 50MHz. Series and parallel capacitors used to fine tune the crystal load to the circuit load. Crystal Cst XIN XOUT 1 Cpt 8 Cpt – Series Capacitor, used to lower circuit load to match crystal load. Raises frequency offset. This can be eliminated by using a crystal with a Cload of equal or greater value than the oscillator. – Parallel Capacitors, Used to raise the circuit load to match the crystal load. Lowers frequency offset. 47745 Fremont Blvd., Fremont, California 94538 Tel (510) 492-0990 Fax (510) 492-0991 www.phaselink.com Rev 4/2/07 Page 4 (Preliminary) PL610-01 1.8V to 3.3V, 1MHz to 130MHz XO IC ELECTRICAL SPECIFICATIONS ABSOLUTE MAXIMUM RATINGS PARAMETERS SYMBOL MIN.
