PL135-67QC-R

PL135-67 Low Power, 1.62V to 3.63V, 10M Hz to 40M Hz, 1:6 Oscillat or Fanout Buffer FEATURES DESCRIPTION  Advanced Oscillator Design for Wide Frequency Coverage  6 LVCMOS Outputs with 2 Output Enable Pins  8mA Output Drive Strength  Input/Output Frequency: o Fundamental Crystal: 10MHz to 40MHz  Very Low Jitter and Phase Noise  Low Current Consumption  Single 1.62V to 3.63V Power Supply  Available in QFN-16L and TSSOP-16L GREEN/RoHS Compliant Packages The PL135-67 is an advanced oscillator fanout buffer design for high performance, low-power, small formfactor applications. The PL135-67 accepts a fundamental input crystal of 10MHz to 40MHz and produces six outputs of the same frequency, two with their own Output Enable functions. Offered in a small 3 x 3mm QFN or TSSOP package, the PL135-67 offers the best phase noise and jitter performance and lowest power consumption of any comparable IC.

With a capacitive load this equals ringing! - Long trace = Transmission Line. Without proper termination this will cause reflections (looks like ringing). - Design long traces as “striplines” or “microstrips” with defined impedance. - Match trace at one side to avoid reflections bouncing back and forth. - Addition of a ferrite bead in series with V DD can help prevent noise from other board sources - Value of decoupling capacitor is frequency dependant. Typical value to use is 0.1F. Crystal Tuning Circuit Series and parallel capacitors used to fine tune the crystal load to the circuit load. Typical CMOS termination Place Series Resistor as close as possible to CMOS output CMOS Output Buffer (Typical buffer impedance 20Ω) - Multiple V DD pins should be decoupled separately for best performance. Crystal To CMOS Input 50Ω line Cst Series Resistor Use value to match output buffer impedance to 50Ω trace. Typical value 30Ω XIN XOUT 1 8 Cpt Cpt CST – 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. CPT – Parallel Capacitors, Used to raise the circuit load to match the crystal load. Lowers frequency offset. ELECTRICAL SPECIFICATIONS ABSOLUTE MAXIMUM RATINGS PARAMETERS SYMBOL MIN. MAX.
