However, 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-15, as shown in diagram ‘2’, below.

PCB LAYOUT CONSIDERATIONS FOR PERFORMANCE OPTIMIZATION The following guidelines are to assist you with a performance optimized PCB design: - Keep all the PCB traces to PL611s-15 as short as possible, as well as keeping all other traces as far away from it as possible. - When a reference input clock is generated from a crystal (see diagram above), place the PL611s-15 ‘FIN’ as close as possible to the ‘Xout’ crystal pin. This will reduce the crosstalk between the reference input and the other signals. - Place the Loop Filter (LF) components as close to the package pin of PL611s-15 as possible. - Place a 0.01µF~0.1µF decoupling capacitor between VDD and GND, on the component side of the PCB, close to the VDD pin. 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 50Ω 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 the application note on how to design outputs driving long traces or the Gerber files for the PL611s-15 layout. 4 7745 Fremont Blvd., Fremont, California 94538 Tel (510) 492-0990 Fax (510) 492-0991 w ww.phaselink.com R ev 07/18/06 Page 4 ( Preliminary) PL611s-15 1 .8V-3.3V PicoPLL TM 3 2K Programmable Clock P ACKAGE DRAWINGS (GREEN PACKAGE COMPLIANT) SOT23-6 L Symbol A A1 A2 b c D E H L e SC70-6L Symbol A A1 A2 b c D E H L e DFN-6L D1 Dimension in MM Min.
