NB3H5150-01 2.5V / 3.3V Low Noise Multi-Rate Clock Generator Description The NB3H5150−01 is a high performance Multi−Rate Clock generator which simultaneously synthesizes up to four different frequencies from a single PLL using a 25 MHz input reference. The reference frequency can be provided by a crystal, LVCMOS/LVTTL, LVPECL, HCSL or LVDS differential signals. The REFMODE pin will select the reference source. Three output banks (CLK1A/CLK1B to CLK3A/CLK3B) produce user selectable frequencies of: 33.33 MHz, 50 MHz, 100 MHz, 125 MHz, or 156.25 MHz and have ultra−low noise/jitter performance of less than 0.3 ps. The fourth output bank (CLK4A/CLK4B) can produce the following integer and FRAC−N frequencies in pin−strap mode: 25 MHz, 33.33 MHz, 66.66 MHz, 100 MHz, 125 MHz, 133.33 MHz, 156.25 MHz or 161.1328 MHz. Each output block can create two single−ended in−phase LVCMOS outputs or one differential pair of LVPECL outputs. Each of the four output blocks is independently powered by a separate VDDO, 2.5 V/3.3 V for LVPECL, 1.8 V/2.5 V/3.3 V for LVCMOS. The serial (I2C and SMBUS) interface can be used to load register files into the NB3H5150−01 to program a variety of functions including the frequencies and output levels of each output which can be individually enabled and disabled.

See Table 2. Ground – Negative Power Supply is connected via the Exposed Pad . The Exposed Pad (EP) on the QFN−32 package bottom is thermally connected to the die for improved heat transfer out of package. The exposed pad must be attached to a heat sinking conduit. The pad is electrically connected to the die,carries all power supply return currents and must be electrically connected to GND. 1. All VDD, AVDDn, VDDOn, EP (GND) pins must be externally connected to a power supply for proper operation. VDD and AVDDn must all be at the same voltage. NB3H5150−01 BASIC OPERATION The I2C interface pins, SCL and SDA, are used to load register files into the NB3H5150−01. These register files will configure the internal registers to achieve an expanded selection of output frequencies and levels combinations for each of the four output blocks. Subsequent changes in the registers can then be performed with another register file to modify any of the output frequencies or output modes. Introduction The NB3H5150−01 is a Multi−Rate Clock Generator. The clock reference for the PLL can be either a 25 MHz crystal, single−ended LVCMOS or LVTTL signal or a differential LVPECL, LVDS or HCSL signal. There are two modes of operation for the NB3H5150−01, Pin−Strap and I2C. In the Pin−Strap Mode, the user can select any of the defined output frequencies for each of the four output banks as specified in Tables 3 and 4 via the three−level Frequency Select pins: FS1, FS2, FS3, FS4A and FS4B. In the I2C mode, the user can select one of the approved register files in Table 5. Each register file is an expanded selection of output frequencies and level combinations, output enable/disable and bypass mode functions. OE, Output Enable An OE, Output Enable/Disable function is available only in the I2C mode by loading a register file, such that any individual output bank can be enabled or disabled. In LVCMOS modes outputs will disable LOW for CLKnA and CLKnB, while the LVPECL mode outputs will disable CLKnA = Low and CLKnB = High. CLKnA & CLKnB − Output Frequency and Output Level Selection Mixed Mode Control (MMC) In the I2C mode, the Mixed Mode Control (MMC) pin is used for a combination of FSn settings and I2C settings to control the CLK(n) outputs’ function as defined in Table 7. There are four output banks: CLK1A&B, CLK2A&B and CLK3A&B are integer only divider outputs, whereas CLK4A&B can be set or programmed as an integer or fractional divider. The output levels for each output bank can be LVPECL (differential) or LVCMOS (two single−ended). Output Enable / Disable functions are available in I2C only. CLK1, 2, 3 and 4 outputs are not phase−aligned, in PLL or PLL bypass modes. REFMODE – Select a Crystal or External Clock Input Interface (See Table 2) The REFMODE pin will select the reference input for the CLK_XTAL1 and CLK_XTAL2 pins to use either a crystal, an overdriven single−ended or differential input. When using a crystal, set the REFMODE pin to a LOW. The CLK_XTAL1 and CLK_XTAL2 input pins will accept a 25 MHz crystal. When using a direct−coupled differential input, set the REFMODE pin to a HIGH. Power−On Output Default Upon power−up, all four outputs will be forced to and held at static LVPECL levels (CLKnA = Low, CLKnB = High) until the PLL is stable. The PLL will be stable before any of the output Clocks, CLKnx, are enabled. SDA & SCL/PD - Serial Data Interface – I2C The NB3H5150−01 incorporates a two−wire Serial Data Interface to expand the flexibility and function of the NB3H5150−01 clock generator. www.onsemi.com 4 NB3H5150−01 When REFMODE is HIGH, the CLK_XTAL1 and CLK_XTAL2 differential input pins have internal AC coupling capacitors selected with self−bias circuity for the differential input buffer. This differential buffer will directly accept any differential signal including LVPECL, LVDS, HCSL or CML. Drive the CLK_XTAL1 pin with the true signal and the CLK_XTAL2 pin with the complementary signal. When overdriving the CLK_XTAL1 input pin with a single−ended signal set REFMODE to a HIGH, and connect CLK_XTAL2 to Ground. The input has internal AC coupling capacitor with self−bias circuitry.

Any unused LVCMOS output can be left floating, but there should be no metal trace attached to the package pin. The exposed pad on the bottom side of the package must be connected to Ground. LDO Pins The NB3H5150−01 has integrated low noise 1.8 V Low−Drop−Out (LDO) voltage regulators which provide power internal to the NB3H5150−01. The LDOs require decoupling capacitors in the range of 1 F to 10 F for compensation and high frequency PSR. When powered−down, the device turns off the LDOs and enters a low power shutdown mode consuming less than 1 mA. LVPECL Differential Outputs The differential LVPECL outputs are powered with VDDO = 3.3 V or 2.5 V and must be properly loaded. See Figure 10. Any unused differential output pair should either be left floating or terminated. FTM This is a Factory Test Mode pin and must be connected to the Ground of the application for proper operation. REF Out In the PLL bypass mode available via I2C, the input reference frequency can be routed to CLK1A and CLK1B as phase aligned LVCMOS or differential LVPECL outputs with the same frequency. The output frequency and duty cycle equals the input frequency and duty cycle. PIN−STRAP / FSn Frequency Select MODE: (see Tables 3 and 4) The NB3H5150−01 can be configured to operate in pin−strap mode where the control pins FSnA/B can be set to generate the necessary clock outputs of the device. Prerequisites: ♦ SDA and SCL/PD must be Low at all times while in pin−strap mode to enable FS control. If SDA ever goes High, pin−strap is exited and the only way to go back is to power cycle the device. ♦ Mixed Mode Control pin (MMC) level will be IGNORED. Power Supplies The NB3H5150−01 has several power supply pins: • VDD is the supply voltage for the input and digital core circuitry. • AVDD1, AVDD2 and AVDD3 powers the core analog circuits. VDD = AVDD1 = AVDD2 = AVDD3. • VDDO1, VDDO2, VDDO3 and VDDO4 are individual power supplies for each of the four CLKnA/B output banks. Upon power−up, all four VDDOn pins must be connected to a power supply, even if only one output is being used. Any combination of VDD and VDDOn power supply voltages is allowed. A power supply filtering scheme in Figure 8 is recommended for best device performance. When all VDD, AVDDn and VDDOn pins reach their minimum voltage per Table 10, the NB3H5150−01 will operate at the proper output frequencies. Sequencing: 1. Upon device power−up (assuming SCL is LOW) a. All four CLK(n) frequency and output type selections will be pre−loaded according to the FS pin settings, but all four outputs will be held at static LVPECL levels (CLKnA = Low, CLKnB = High) until the PLL has become stable. b. After the PLL is stable, all CLK(n) output type selections (i.e. LVPECL or LVCMOS) will www.onsemi.com 5 NB3H5150−01 be aware that subsequent change to the FS pin should only change frequency, and not output type. 3. Power off/on cycle will repeat the entire sequence 4. Power Down To initiate the Power−Down mode, the SDA pin must be LOW and remain LOW. If the SCL/PD pin is taken HIGH at any time, the device enters a complete power−down mode with a current consumption of less than 1 mA for the entire device. When SCL/PD is subsequently taken LOW, the device will function as though power were removed and re−applied. That is, sequencing will begin at #1. Power−down is also available via I2C with a register file. become effective and will begin to output the selected frequencies. 2. Subsequent changes to any FS pin(s) will cause the associated CLK(n) output(s) to momentarily go to static levels, and then to resume at the new frequency; CLK(n) will follow the FS(n) pin programmable Tables 3 and 4 for output frequencies and interface levels. Note that in changing from LVPECL to LVCMOS (or vice−versa), output logic levels cannot be guaranteed. This is because the receiver inputs are not likely to change in a given application, and the LVPECL output loading in the application will also not change. It is logical to presume that the output type will be predetermined and fixed. Therefore, in a system/application, the user should FS(n) Pin Programmable Selection of Output Frequencies and Levels Table 3.

CLK4A/4B outputs remain at Static LVPECL Levels. After power up, changes to all pins will be ignored except the SDA and SCL inputs. iv. The FS4A and FS4B pins set the bus address when MMC pin is LOW (see Table 6, I2C Device Address Table). c. The I2C interface can now be used to load register files into the NB3H5150−01. In I2C Mode, configuration of Output Enables, output frequency, output levels of each output, specific block power−down control, bypass mode, etc. are all possible. d. Any outputs which were held in static level mode (described above) will be released for operation. CLK(n) outputs will be active at the programmed frequencies and levels. CLK(n) outputs will react to any subsequent changes to the I2C bus. If any output channel is not programmed, then output is loaded from FSn pins. A Power Cycle will clear all previous register information and I2C mode will repeat to number 1 in the power up sequence. To simplify device configuration, ON Semiconductor provides desktop software, that can be downloaded from http://www.onsemi.com/pub/Collateral/NB3H5150−01_G UI.ZIP which will operate in conjunction with the NB3H5150−01 evaluation board (EVB). The NB3H5150−01 GUI manual can also be found on the web site. When the software is connected to an NB3H5150−01 EVB, it can control the selection of numerous clock output frequencies for each of the four CLK outputs and the output type as well as Output Enable/Disable. Some features that are not available in pin−strap mode can be obtained in I2C mode, such as Output Enable/Disable, By−Pass mode and Power−Down. In addition, output frequency and output levels can also be I2C controlled. The NB3H5150−01 I2C Programming Guide can be found on the NB3H5150−01 web site. This application note provides details on configuring the NB3H5150−01 by writing to registers in the NB3H5150−01 with approved register files through the I2C/SMBus interface. http://www.onsemi.com/pub/Collateral/NB3H5150−01%2 0I2C%20PROGRAMMING%20GUIDE%20%20..PDF The user can select a Register File from the ON Semiconductor website from the NB3H5150−01 I2C Register Files folder.

Upon device power−up. a. All four frequencies and output type selections will be preloaded according to the FSn pin settings, but all four outputs will be held at static LVPECL levels until the PLL has become stable. NOTE: After power up, changes to FS pins will be blocked from controlling device operation. b. Once the PLL is stable, the Mixed Mode Control pin (MMC) is checked: i. If MMC is LOW, all CLK(n) outputs will remain at static LVPECL levels. ii. If MMC is HIGH and FS4A is LOW, CLK1, CLK2, and CLK3 outputs will remain at static LVPECL levels. CLK4A/4B output frequency and output levels will become active after PLL stabilization time according to FS4A and FS4B pin selection in Table 4. After power up, changes to all pins will be ignored. iii.

(See Figures 12 and 13).

(See Figures 17, 18 and 19). Provided that the LVDS receiver can tolerate large input voltage peak to peak amplitude, the 2.5 V LVPECL output can be directly interfaced to an LVDS receiver using proper ECL termination. The 2.5 V LVPECL output will be able to drive an LVDS receiver with or without internal 100 termination resistor.

Via Layout Recommendation for Exposed Pad, QFN−32 Package The exposed pad on the NB3H5150−01 QFN−32 package carries all of the power supply return currents. It is therefore important that the necessary current capability be satisfied, as well as the thermal transfer from the die to the PCB. Figure 20 shows a recommended via layout pattern for the exposed pad. Via spacing = 0.02”, filled vias preferred.
