553S Datasheet Low Skew 1 to 4 Clock Buffer Description Features The 553S is a low skew, single input to four output, clock buffer. The 553S has best in class additive phase Jitter of sub 50 fsec. • • • • • • • • • • • IDT makes many non-PLL and PLL based low skew output devices as well as Zero Delay Buffers to synchronize clocks. Contact us for all of your clocking needs. Low additive phase jitter RMS: 50fs Extremely low skew outputs (50ps) Low cost clock buffer Packaged in 8-SOIC and small 8-DFN package, Pb-free Input/Output clock frequency up to 200MHz Ideal for networking clocks Operating voltages: 1.8V to 3.3V Output Enable mode tri-states outputs Advanced, low power CMOS process Extended temperature range (-40°C to +105°C) 3.3V tolerant input clock Block Diagram Q0 Q1 ICLK Q2 Q3 Output Enable ©2020 Renesas Electronics Corporation 1 January 6, 2020 553S Datasheet Pin Assignments VDD 1 8 OE VDD 1 8 OE Q0 2 7 Q3 Q0 2 7 Q3 Q1 3 6 Q2 Q1 3 6 Q2 GN D 4 5 I CLK GND 4 5 ICLK 8- pi n SOI C 8-pin DFN Pin Descriptions Pin Number Pin Name Pin Type Pin Description 1 VDD Power Connect to +1.8V, +2.5V, or +3.3V. 2 Q0 Output Clock output 0. 3 Q1 Output Clock output 1. 4 GND Power Connect to ground. 5 ICLK Input 6 Q2 Output Clock output 2. 7 Q3 Output Clock output 3. 8 OE Input Clock input. Output Enable. Tri-states outputs when low. Connect to VDD for normal operation. External Components A minimum number of external components are required for proper operation. A decoupling capacitor of 0.01µF should be connected between VDD on pin 1 and GND on pin 4, as close to the device as possible. A 33 series terminating resistor may be used on each clock output if the trace is longer than 1 inch. To achieve the low output skew that the 553S is capable of, careful attention must be paid to board layout. Essentially, all four outputs must have identical terminations, identical loads and identical trace geometries. If they do not, the output skew will be degraded. For example, using a 30 series termination on one output (with 33 on the others) will cause at least 15ps of skew. ©2020 Renesas Electronics Corporation 2 January 6, 2020 553S Datasheet Absolute Maximum Ratings Stresses above the ratings listed below can cause permanent damage to the 553S. These ratings, which are standard values for IDT commercially rated parts, are stress ratings only. Functional operation of the device at these or any other conditions above those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods can affect product reliability. Electrical parameters are guaranteed only over the recommended operating temperature range.

With an integration range of 12kHz to 20MHz, the reference input has about 66fs of RMS phase jitter while the output of 553S has about 76fs of RMS phase jitter. This results in a low Additive Phase Jitter of only 37fs.
