1 / 22 page © Semiconductor Components Industries, LLC, 2009 January, 2009 − Rev. 13 1 Publication Order Number: NBC12429/D NBC12429, NBC12429A 3.3V/5V Programmable PLL Synthesized Clock Generator 25 MHz to 400 MHz Description The NBC12429 and NBC12429A are general purpose, Phase−Lock−Loop(PLL) based synthesized clock sources. The VCO will operate over a frequency range of 200 MHz to 400 MHz. The VCO frequency is sent to the N−output divider, where it can be configured to provide division ratios of 1, 2, 4, or 8. The VCO and output frequency can be programmed using the parallel or serial interfaces to the configuration logic. Output frequency steps of 125 kHz, 250 kHz, 500 kHz, or 1.0 MHz can be achieved using a 16 MHz crystal, depending on the output dividers. The PLL loop filter is fully integrated and does not require any external components. Features • Best−in−Class Output Jitter Performance, ±20 ps Peak−to−Peak • 25 MHz to 400 MHz Programmable Differential PECL Outputs • Fully Integrated Phase−Lock−Loop with Internal Loop Filter • Parallel Interface for Programming Counter and Output Dividers During Powerup • Minimal Frequency Overshoot • Serial 3−Wire Programming Interface • Crystal Oscillator Interface • Operating Range: VCC = 3.135 V to 5.25 V • CMOS and TTL Compatible Control Inputs • Pin and Function Compatible with Motorola MC12429 and MPC9229 • 0°C to 70°C Ambient Operating Temperature (NBC12429) • −40°C to 85°C Ambient Operating Temperature (NBC12429A) • Pb−Free Packages are Available MARKING DIAGRAMS PLCC−28 FN SUFFIX CASE 776 NBC12429xG AWLYYWW 128 See detailed ordering and shipping information in the package dimensions section on page 18 of this data sheet.
