    产品信息

    The NB3H5150 is a high performance Multi−Rate Clock generatorwhich simultaneously synthesizes up to four different frequenciesfrom a single PLL using a 25 MHz input reference. The referencefrequency can be provided by a crystal, LVCMOS/LVTTL, LVPECL,HCSL or LVDS differential signals. The REFMODE pin will selectthe reference source.Three output banks (CLK1A/CLK1B to CLK3A/CLK3B) produceuser selectable frequencies of: 25 MHz, 33.33 MHz, 50 MHz,100 MHz, 125 MHz, or 156.25 MHz and have ultra−low noise/jitterperformance of less than 0.3 ps.The fourth output bank (CLK4A/CLK4B) can produce thefollowing integer and FRAC−N frequencies in pin−strap mode:33.33 MHz, 66.66 MHz, 100 MHz, 106.25 MHz, 125 MHz,133.33 MHz, 155.52 MHz, 156.25 MHz or 161.1328 MHz.More programmable frequencies are available via the I2C interfacewith jitter performance of less than 1 ps. Detailed registereddescriptions will be available in a future application note.Each output block can create two single−ended in−phase LVCMOSoutputs or one differential pair of LVPECL outputs.Each of the four output blocks is independently powered by aseparate VDDO, 2.5 V/3.3 V for LVPECL, 1.8 V/2.5 V/3.3 V forLVCMOS.The serial (I2C and SMBUS) interface can program a variety offunctions including the frequencies and output levels of each dividerblock which can be individually enabled and disabled.
