Timer Function Description 1. The timer function can be used together with the DFC -Dynamic Frequency Control function or with another PLL frequency programming. 2. The timer provides 4 different delay times by two bits selection: 0.5 sec – 1 sec – 2 sec – 4 sec. 3. The timeout flag will be set when timer times out and the flag can be cleared by writing 0 to timer enable bit. 4. When timer times out, RESET pin can generate a 250ms pulse signal if RESET control bit is enabled. 5. When timer times out, DFC stage will switch back to DFC00 setting if DFC function is enabled, and DFC function will be disabled after RESET. Figure 5.

See below reference circuit for details. Crystal Input (X1/X2) The crystal oscillators should be fundamental mode quartz crystals; overtone crystals are not suitable. Crystal frequency should be specified for parallel resonance with 40MHz maximum. A crystal manufacturer will calibrate its crystals to the nominal frequency with a certain load capacitance value. When the oscillator load capacitance matches the crystal load capacitance, the oscillation frequency will be accurate as 0 PPM. When the oscillator load capacitance is lower than the crystal load capacitance, the oscillation frequency will be higher than nominal. In order to get an accurate oscillation frequency, the matching the oscillator load capacitance with the crystal load capacitance is required. To set the oscillator load capacitance, 5P35023 has built-in two programmable tuning capacitors inside the chip, one at XIN and one at XOUT. They can be adjusted independently. The value of each capacitor is composed of a fixed capacitance amount plus a variable capacitance amount set with the XTAL[7:0] register. Adjustment of the crystal tuning capacitors allows for maximum flexibility to accommodate crystals from various manufacturers. The range of tuning capacitor values available are in accordance with the following table. ©2019 Integrated Device Technology, Inc. 10 October 4, 2019 5P35023 Datasheet Table 13. Programmable Tuning Caps Parameter Bits Range Minimum (pF) Maximum (pF) Xtal [7:0] 4×2 +1 / +2 / +4 / +8pF 0 15pF XTAL[4:0] = (XTAL CL - 7pF) × 2 (Eq.1) Equation 1 and the table of XTAL[7:0] tuning capacitor characteristics show that the parallel tuning capacitance can be set between 4.5pF to 12.5pF with a resolution of 0.25pF. For a crystal CL = 8pF, where CL is the parallel capacity specified by the crystal vendor that sets the crystal frequency to the nominal value. Under the assumptions that the stray capacity between the crystal leads on the circuit board is zero and that no external tuning caps are placed on the crystal leads, then the internal parallel tuning capacity is equal to the load capacity presented to the crystal by the device. The internal load capacitors are true parallel-plate capacitors for ultra-linear performance. Parallel-plate capacitors were chosen to reduce the frequency shift that occurs when non-linear load capacitance interacts with load, bias, supply, and temperature changes. External non-linear crystal load capacitors should not be used for applications that are sensitive to absolute frequency requirements. Spread Spectrum The 5P35023 supports spread spectrum clocks from PLL1 and PLL2; the PLL1 built-in with analog spread spectrum and PLL2 has digital spread spectrum. Analog Spread Spectrum Refer to programming guide. ©2019 Integrated Device Technology, Inc. 11 October 4, 2019 5P35023 Datasheet Digital Spread Spectrum Figure 6. Digital Spread Spectrum N  Fvco 2 * Fout period step   Fpfd 2 * Fss N * SSamount period Down spread or spread off N = Fvco/Fpfd Center Spread N = Nssoff + N × SSamount/2 N: include integer and fraction Fvco: VCOs frequency Fpfd: PLLs pfd frequency Fss: spread modulation rate SSamount: spread percentage The black line is for the down spread; N will decrease to make the center frequency is lower than spread off. The blue line is for the center spread; there is an offset put on divider ratio to make the center frequency keep same as spread off. Example: 0.5% down spread at 32kHz modulation rate. VBAT The 5P35023 supports a low-power operation 32.768kHz RTC clock with only a coin cell battery supply. The coin cell battery power capacitance is usually 170mAhr or higher, with less than 2μA* low-power DCO operation mode will support application up to few years clock source for date/time keeping circuit (RTC). When main power exists (for example, VDD33 and VDDA), the 5P35023 will switch DCO power source to main power to save battery power. Table 14.

The VCO frequency changes are under control instead of free-run to targeted frequency. PLL Features and Descriptions Table 15.

I2C Mode Operations The device acts as a slave device on the I2C bus using one of the four I2C addresses (0xD0, 0xD2, 0xD4, or 0xD6) to allow multiple devices to be used in the system. The interface accepts byte-oriented block write and block read operations. Two address bytes specify the register address of the byte position of the first register to write or read. Data bytes (registers) are accessed in sequential order from the lowest to the highest byte (most significant bit first). Read and write block transfers can be stopped after any complete byte transfer. During a write operation, data will not be moved into the registers until the STOP bit is received, at which point, all data received in the block write will be written simultaneously. For full electrical I2C compliance, it is recommended to use external pull-up resistors for SDATA and SCLK. The internal pull-down resistors have a size of 100kΩ typical. ©2019 Integrated Device Technology, Inc. 27 October 4, 2019 5P35023 Datasheet Figure 10.

Glossary of Features Table 37. Glossary of Features Term Function Description Apply to DFC Dynamic Frequency Control; from selected PLL to support four VCO frequencies; means two different output frequencies by assigned H/W pin state changes (H-L or L-H) needs to have frequency change Glitch-Free function in order to not crash application system. PLL2 ORT Overshoot Reduction; when the DFC dynamic frequency change is functional, the VCO changes frequencies smoothly to target frequency without overshoot or undershoot. PLL2 OE Output enable function; each output can be controlled by assigned OE pin and the dedicated OE pin can be OTP programmable as global Power Down function (PD#) or Output Enable (OE) or Proactive Power Saving function (PPS) or RESET pin function. OE1–3 SS Spread spectrum clock. Slew Rate PPS PLL1/PLL2 LVCMOS outputs with slew rate control – slow and fast. Proactive Power Saving; utilize OE pin as monitor pin for end device X2 clock status. See PPS – Proactive Power Saving Function description for details.
