Quad-Frequency Programmable VCXO IDT8N4QV01 REV G DATA SHEET General Description Features The IDT8N4QV01 is a Quad-Frequency Programmable VCXO with very flexible frequency and pull-range programming capabilities. The device uses IDT’s fourth generation FemtoClock® NG technology for an optimum of high clock frequency and low phase noise performance. The device accepts 2.5V or 3.3V supply and is packaged in a small, lead-free (RoHS 6) 10-lead ceramic 5mm x 7mm x 1.55mm package. • • Fourth generation FemtoClock® NG technology • Four power-up default frequencies (see part number order codes), re-programmable by I2C • I2C programming interface for the output clock frequency, APR and internal PLL control registers Besides the 4 default power-up frequencies set by the FSEL0 and FSEL1 pins, the IDT8N4QV01 can be programmed via the I2C interface to any output clock frequency between 15.476MHz to 866.67MHz and from 975MHz to 1,300MHz to a very high degree of precision with a frequency step size of 435.9Hz ÷N (N is the PLL output divider). Since the FSEL0 and FSEL1 pins are mapped to 4 independent PLL, P, M and N divider registers (P, MINT, MFRAC and N), reprogramming those registers to other frequencies under control of FSEL0 and FSEL1 is supported. The extended temperature range supports wireless infrastructure, telecommunication and networking end equipment requirements. • • Frequency programming resolution is 435.9Hz ÷N • • • • One 2.5V or 3.3V LVDS differential clock output • RMS phase jitter @ 156.25MHz (1kHz - 40MHz): 0.594ps (typical) • • • 2.5V or 3.3V supply voltage modes Programmable clock output frequency from 15.476MHz to 866.67MHz and from 975MHz to 1,300MHz Absolute pull-range (APR) programmable from ±4.5ppm to ±754.5ppm Two control inputs for the power-up default frequency LVCMOS/LVTTL compatible control inputs RMS phase jitter @ 156.25MHz (12kHz - 20MHz): 0.494ps (typical) -40°C to 85°C ambient operating temperature Available in Lead-free (RoHS 6) package Block Diagram Q nQ ÷N 114.285 MHz 2 A/D FSEL1 FSEL0 SCLK SDATA OE 7 Pulldown Pulldown 7 25 Configuration Register (ROM) (Frequency, APR, Polarity) Pullup I2C Control Pullup VC 1 8 VDD OE 2 7 nQ GND 3 ÷MINT, MFRAC VC 9 SDATA FemtoClock® NG VCO 1950-2600MHz 6 Q FSEL1 5 PFD & LPF FSEL0 4 ÷P OSC 10 SCLK Pin Assignment IDT8N4QV01 REV G DATA SHEET 10-lead ceramic 5mm x 7mm x 1.55mm package body CD Package Top View Pullup IDT8N4QV01GCD MARCH 6, 2012 1 ©2012 Integrated Device Technology, Inc.

IDT8N4QV01 REV G DATA SHEET QUAD-FREQUENCY PROGRAMMABLE-VCXO Principles of Operation The block diagram consists of the internal 3rd overtone crystal and oscillator which provide the reference clock fXTAL of either 114.285MHz or 100MHz. The PLL includes the FemtoClock NG VCO along with the Pre-divider (P), the feedback divider (M) and the post divider (N). The P, M, and N dividers determine the output frequency based on the fXTAL reference and must be configured correctly for proper operation. The feedback divider is fractional supporting a huge number of output frequencies. The configuration of the feedback divider to integer-only values results in an improved output phase noise characteristics at the expense of the range of output frequencies. In addition, internal registers are used to hold up to four different factory pre-set P, M, and N configuration settings. These default pre-sets are stored in the I2C registers at power-up. Each configuration is selected via the the FSEL[1:0] pins and can be read back using the SCLK and SDATA pins. As identified previously, the configurations of P, M (MINT & MFRAC) and N divider settings are stored the I2C register, and the configuration loaded at power-up is determined by the FSEL[1:0] pins. Table 4 Frequency Selection Input The user may choose to operate the device at an output frequency different than that set by the factory. After power-up, the user may write new P, N and M settings into one or more of the four configuration registers and then use the FSEL[1:0] pins to select the newly programmed configuration. Note that the I2C registers are volatile and a power supply cycle will reload the pre-set factory default conditions. FSEL1 FSEL0 Selects Register 0 (def.) 0 (def.) Frequency 0 P0, MINT0, MFRAC0, N0 0 1 Frequency 1 P1, MINT1, MFRAC1, N1 1 0 Frequency 2 P2, MINT2, MFRAC2, N2 1 1 Frequency 3 P3, MINT3, MFRAC3, N3 Frequency Configuration An order code is assigned to each frequency configuration programmed by the factory (default frequencies). For more information on the available default frequencies and order codes, please see the Ordering Information Section in this document. For available order codes, see the FemtoClock NG Ceramic-Package XO and VCXO Ordering Product Information document. If the user does choose to write a different P, M, and N configuration, it is recommended to write to a configuration which is not currently selected by FSEL[1:0] and then change to that configuration after the I2C transaction has completed. Changing the FSEL[1:0] controls results in an immediate change of the output frequency to the selected register values. The P, M, and N frequency configurations support an output frequency range 15.476MHz to 866.67MHz and 975MHz to 1,300MHz. For more information and guidelines on programming of the device for custom frequency configurations, the register description, the pull-range programming and the serial interface description, see the FemtoClock NG Ceramic 5x7 Module Programming Guide. The devices use the fractional feedback divider with a delta-sigma modulator for noise shaping and robust frequency synthesis capability. The relatively high reference frequency minimizes phase noise generated by frequency multiplication and allows more efficient shaping of noise by the delta-sigma modulator. The output frequency is determined by the 2-bit pre-divider (P), the feedback divider (M) and the 7-bit post divider (N). The feedback divider (M) consists of both a 7-bit integer portion (MINT) and an 18-bit fractional portion (MFRAC) and provides the means for high-resolution frequency generation. The output frequency fOUT is calculated by: 1 MFRAC + 0.5 f OUT = f XTAL ------------ MINT + ----------------------------------- (1) 18 PN 2 The four configuration registers for the P, M (MINT & MFRAC) and N dividers which are named Pn, MINTn, MFRACn and Nn with n = 0 to 3. “n” denominates one of the four possible configurations.

IDT8N4QV01 REV G DATA SHEET QUAD-FREQUENCY PROGRAMMABLE-VCXO Applications Information Recommendations for Unused Input Pins Inputs: LVCMOS Select Pins All control pins have internal pulldowns; additional resistance is not required but can be added for additional protection. A 1k resistor can be used. LVDS Driver Termination For a general LVDS interface, the recommended value for the termination impedance (ZT) is between 90 and 132. The actual value should be selected to match the differential impedance (Z0) of your transmission line. A typical point-to-point LVDS design uses a 100 parallel resistor at the receiver and a 100 differential transmission-line environment. In order to avoid any transmission-line reflection issues, the components should be surface mounted and must be placed as close to the receiver as possible. IDT offers a full line of LVDS compliant devices with two types of output structures: current source and voltage source. The standard termination schematic as shown in Figure 1A can be used with either type of output structure. Figure 1B, which can also be used with both output types, is an optional termination with center tap capacitance to help filter common mode noise. The capacitor value should be approximately 50pF. If using a non-standard termination, it is recommended to contact IDT and confirm if the output structure is current source or voltage source type. In addition, since these outputs are LVDS compatible, the input receiver’s amplitude and common-mode input range should be verified for compatibility with the output.

IDT8N4QV01 REV G DATA SHEET QUAD-FREQUENCY PROGRAMMABLE-VCXO Power Considerations This section provides information on power dissipation and junction temperature for the IDT8N4QV01. Equations and example calculations are also provided. 1. Power Dissipation. The total power dissipation for the IDT8N4QV01 is the sum of the core power plus the power dissipated in the load(s). The following is the power dissipation for VDD = 3.3V + 5% = 3.465V, which gives worst case results. • Power (core)MAX = VDD_MAX * IDD_MAX = 3.465V * 160mA = 554.4mW 2. Junction Temperature. Junction temperature, Tj, is the temperature at the junction of the bond wire and bond pad directly affects the reliability of the device. The maximum recommended junction temperature is 125°C. Limiting the internal transistor junction temperature, Tj, to 125°C ensures that the bond wire and bond pad temperature remains below 125°C. The equation for Tj is as follows: Tj = JA * Pd_total + TA Tj = Junction Temperature JA = Junction-to-Ambient Thermal Resistance Pd_total = Total Device Power Dissipation (example calculation is in section 1 above) TA = Ambient Temperature In order to calculate junction temperature, the appropriate junction-to-ambient thermal resistance JA must be used. Assuming no air flow and a multi-layer board, the appropriate value is 49.4°C/W per Table 7 below. Therefore, Tj for an ambient temperature of 85°C with all outputs switching is: 85°C + 0.554W * 49.4°C/W = 112.4°C. This is below the limit of 125°C. This calculation is only an example. Tj will obviously vary depending on the number of loaded outputs, supply voltage, air flow and the type of board (multi-layer). Table 7.
