SL23EP04 Low Jitter and Skew 10 to 220 MHz Zero Delay Buffer (ZDB) Key Features Description 10 to 220 MHz operating frequency range Low output clock skew: 60ps-typ Low output clock Jitter: Low part-to-part output skew: 150 ps-typ 3.3V to 2.5V power supply range Low power dissipation: - 12 mA-typ at 66MHz and VDD=3.3V - 10 mA-typ at 66MHz and VDD=2.5V One input drives 4 outputs Multiple configurations and drive options SpreadThru™ PLL that allows use of SSCG Available in 8-pin SOIC package Available in Commercial and Industrial grades The SL23EP04 is a low skew, low jitter and low power Zero Delay Buffer (ZDB) designed to produce up to four (4) clock outputs from one (1) reference input clock, for high speed clock distribution applications. The product has an on-chip PLL and a feedback pin (FBK) which can be used to obtain feedback from any one of the 4 output clocks. The SL23EP04 offers X/2,1X and 2X frequency options at the output with respect to input reference clock. Refer to the “Product Configuration Table” for the details of these options. The SL23EP04-1H and -2H High Drive version operates up to 220 MHz and 200MHz at 3.3 and 2.5V power supplies respectively. The standard versions -1 and -2 operate up to 167MHz and 135MHz at 3.3V and 2.5V power supplies respectively with CL=15pF output load. The SL23EP04 enter into Power Down (PD) mode if the input at CLKIN is DC (GND to VDD). In this state all 4 output clocks are tri-stated and the PLL is turned off, leading to 8μA-typ power supply current draw.

These drive options enable the user to control The product includes an on-chip high performance PLL load levels, frequency range and EMI levels. Refer to the that locks into the input reference clock and produces electrical tables for the details of the drive levels. four (4) output clock drivers tracking the input reference clock for systems requiring clock distribution. Skew and Zero Delay in addition to FBK pin used for internal PLL feedback, All outputs should drive the similar load to achieve outputthere are two (2) banks with two (2) outputs in each bank, to-output skew and input-to-output delay specifications as bringing the number of total available output clocks to given in the switching electrical tables. However, the delay four (4). between input and outputs can be adjusted by changing the load at FBK pin relative to the banks A and B clocks Input and output Frequency Range since FBK pin is the feedback to the internal PLL. The input and output frequency is the same (1x) for SL23EP04-1 and -1H versions. For SL23EP04-2 and In addition, the input reference clock rise and fall time 2H versions, the output frequency is 1/2x, 1x or 2x of should be similar to the output rise and fall time to obtain the CLKIN as given in the “Available SL23EP04 the best skew results. Configurations” Table 1. But, the frequency range depends on VDD, drive levels and CL (Load Power Supply Range (VDD) Capacitance) as given in the electrical specifications tables. The SL23EP04 is designed to operate from 3.3V (3.63Vmax) to 2.5V (2.25V-min) VDD power supply range. An When the input clock frequency is DC (from GND to internal on-chip voltage regulator is used to provide to VDD), this input state is detected by an input level detection circuitry and all four (4) clock outputs are forced PLL constant power supply of 1.8V internally. This leads to a consistent and stable PLL electrical performance in to Hi-Z. The PLL is shutdown to save power. In this terms of skew, jitter and power dissipation. The shutdown state, the product draws less than 12 μA SL23EP04 I/O is powered by using VDD. (8 μA –typ) supply current. SpreadThru™ Feature If a Spread Spectrum Clock (SSC) were to be used as an input clock, the SL23EP04 is designed to pass the modulated Spread Spectrum Clock (SSC) signal from its reference CLKIN input to the output clocks. The same spread spectrum characteristics at the input are passed through the PLL and drivers without any degradation in spread percent (%), spread profile and modulation frequency.

Place the capacitor on the component side of the PCB as close to the VDD pin as possible. The PCB trace to the VDD pin and to the GND via should be kept as short as possible. Do not use vias between the decoupling capacitor and the VDD pin. Series Termination Resistor: A series termination resistor is recommended if the distance between the output clocks and the load is over 1 ½ inch. The nominal impedance of the clock outputs is given in the Operating Condition Tables. Place the series termination resistors as close to the clock outputs as possible. Zero Delay and Skew Control: All outputs and CLKIN pins should be loaded with the same load to achieve “Zero Delay” between the CLKIN and the outputs. The FBK pin is connected to PLL internally on-chip for feedback and should be connected to one of to output clocks externally. For applications requiring zero input/output delay, the load at the all output pins including the FBK pin must be the same. If any delay adjustment is required, the capacitance at the FBK pin could be increased or decreased to increase or decrease the delay between Bank A and B clocks relative to CLKIN. For minimum pin-to-pin skew, the external load at all the Bank A and B clocks must be the same. In addition, the rise and fall time of the reference clock at CLKIN pin should be similar to rise and fall times at the CLKA and CLK B bank outputs.
