4 / 9 page (Preliminary)PL611s-17 1.8V-3.3V PicoPLL TM KHz to MHz Programmable Clock 47745 Fremont Blvd., Fremont, California 94538 Tel (510) 492-0990 Fax (510) 492-0991 www.phaselink.com Rev 01/04/07 Page 4 APPLICATION RECOMMENDATIONS FOR PL611s-17 PL611s-17 can accept a reference input >10kHz and produce a clock output in the MHz range, as shown in the diagram ‘1’, below. Also, to save costs in consumer product system designs and for greater area optimization, it is possible to use the XOUT of the RTC crystal (32.768KHz) as the reference input to the PL611s-17, as shown in diagram ‘2’, below. Diagram ‘1’ Diagram ‘2’ Note: An AC Coupling Cap may be required if RTC Clock amplitude is too small. GUIDELINES FOR EXTERNAL COMPONENT SELECTION For the optimum performance, an accurate external loop filter capacitor must be selected. A general guideline for selecting this component based on the input frequency is shown in the table below. Input Frequency Capacitor Value 3MHz ~ 200MHz 1.0nF 300KHz ~ 10MHz 1.0nF 30KHz ~ 1.0MHz 4.7nF 10KHz ~ 100KHz 47nF The optimal way to choose the value is using the following formula: C(nF) = 0.8 + M/280 Where C = Loop Filter Capacitor value (in nF) M = M counter value. Provided by PhaseLink with device samples. Notes: * Find the closest commercially available value. Values in the E12 range with 5% tolerance are acceptable. * With possible M-counter values between 1 and 65536, the capacitor value is expected in the range 820pF thru 220nF. 32.768 KHz C1 C2 ASIC ASIC ASIC ASIC XIN XOUT XIN XOUT REFIN MHZ CLK (Any Frequency) 1.8~3.3V LF LFGND OE, PDB FSEL, CLK1 1 2 3 6 5 4 REFIN MHZ CLK (Any Frequency) 1.8~3.3V LF LFGND OE, PDB FSEL, CLK1 1 2 3 6 5 4 |
