DATASHEET 525-01/02 USER CONFIGURABLE CLOCK Description Features The ICS525-01/02 are the most flexible way to generate a high-quality, high-accuracy, high-frequency clock output from an inexpensive crystal or clock input. The user can configure the device to produce nearly any output frequency from any input frequency by grounding or floating the select pins. Neither microcontroller, software, nor device programmer are needed to set the frequency. Using Phase-Locked Loop (PLL) techniques, the device accepts a standard fundamental mode, inexpensive crystal to produce output clocks up to 250MHz. It can also produce a highly accurate output clock from a given input clock, keeping them frequency locked together. • Packaged in 28-pin SSOP (150 mil body) or 28-pin • VFQFPN (4x4mm body) Industrial and commercial versions available in Pb (lead) free package • User determines the output frequency by setting all • • • • • • • • • • • • For similar capability with a serial interface, use the 307. For simple multipliers to produce common frequencies, refer to the 50x family of parts, which are smaller and more cost effective. These products are intended for clock generation. They have low output jitter (variation in the output period), but input to output skew and jitter are not defined nor guaranteed. For applications which require defined input to output timing, use the 527-01. internal dividers Eliminates need for custom oscillators No software needed Online calculator determines register settings Pull-ups on all select inputs Input crystal frequency of 5 – 27 MHz Input clock frequency of 2 – 50 MHz Very low jitter Duty cycle of 45/55 up to 200MHz Operating voltage of 3.0V or 5.5V Ideal for oscillator replacement Industrial temperature version available For Zero Delay, refer to the 527 Block Diagram VDD 2 PD X1/ICLK Crystal or clock input Crystal Oscillator Reference Divider X2 VCO Output Divider VCO Divider Optional crystal capacitors 7 R6:R0 © 2021 Renesas Electronics Corporation CLK Phase Comparator, Charge Pump, and Loop Filter 9 V8:V0 1 REF 2 GND 3 S2:S0 525-01/02 AUGUST 23, 2021 525-01/02 USER CONFIGURABLE CLOCK CLOCK MULTIPLIER 27 R3 S0 3 26 R2 S1 4 25 R1 S2 5 24 VDD 6 X1/ICLK REF 2 VDD R6 R0 R4 R1 28 R2 1 R3 R5 R4 Pin Assignments 28 27 26   25 24 23 22 R5 1 21 CLK R0 R6 2 20 GND 23 VDD S0 3 19 PD 7 22 REF X2 8 21 CLK S1 4 18 V8 GND 9 20 GND S2 5 17 V7 V0 10 19 PD VDD 6 16 V6 V1 11 18 V8 V2 12 17 V7 X1/CLKIN 7 15 V5 V3 13 16 V6 V4 14 15 V5 12 13 14 V3 V4 11 V2 GND 10 V1 9 V0 8 X2 EPAD 28-pin VFQFPN 28-pin SSOP Pin Descriptions Pin Number Pin Name Pin Type 1, 2, 24-28 R5, R6, R0-R4 I(PU) Reference divider word input pins determined by user.

The capacitor must be connected close to the device to minimize lead inductance. Reference Divider Word (RDW) = 0 to 127 (0 not permitted for 525-01) VCO Divider Word (VDW) = 0 to 511 (0, 1, 2, 3 not permitted for 525-01) External Resistors Output Divider (OD) = values on pages 3-4 A 33series termination resistor should be used on the CLK and REF pins. Also, the following operating ranges should be observed: Crystal Load Capacitors 1. The output frequency must be in the ranges listed on pages 3-4. The approximate total on-chip capacitance for a crystal is 16 pF, so a parallel resonant, fundamental mode crystal with this value of load (correlation) capacitance should be used. For crystals with a specified load capacitance greater than 16 pF, crystal capacitors may be connected from each of the pins X1 and X2 to Ground as shown in the block diagram. The value (in pF) of these crystal caps should be (CL -16)*2, where CL is the crystal load capacitance in pF. These external capacitors are only required for applications where the exact frequency is critical. For a clock input, connect to X1 and leave X2 unconnected (no capacitors on either). 2. The phase detector frequency must be above 200 kHz. InputFrequency 200kHz < ---------------------------------------------- RDW + 2  Since all of the inputs have pull-up resistors, it is only necessary to ground the pins that need to be set to zero. Determining the Output Frequency Which Part to Use? Users have full control in setting the desired output frequency over the range shown in the tables on pages 3-4. To replace a standard oscillator, users should connect the divider select input pins directly to ground (or VDD, although this is not required because of internal pull-ups) during Printed Circuit Board layout. The 525 will automatically produce the correct frequency when all components are soldered. It is also possible to connect the inputs to parallel I/O ports to switch frequencies. By choosing divides carefully, the number of inputs which need to be changed can be minimized. Observe the restrictions on allowed values of VDW and RDW. The 525-01 is the original configurable clock. The 525-02 has a higher maximum output frequency and a slightly different set of output dividers. To determine the best combination of VCO, reference, and output divide, use the Calculator on our web site. Configuration Pin Settings The output of the 525 can be determined by the following simple equation: © 2021 Renesas Electronics Corporation 4 525-01/02 AUGUST 23, 2021 525-01/02 USER CONFIGURABLE CLOCK CLOCK MULTIPLIER Absolute Maximum Ratings Stresses above the ratings listed below can cause permanent damage to the ICS525-01/02.
