Renesas Electronics Corporation Clock/Timing - Clock Generators, PLLs, Frequency Synthesizers MPC92439EIR2

The MPC92439EIR2 is a PLL-based clock synthesizer designed for high-performance applications in telecom, networking, and computing. It operates with a supply voltage of 3.3 V and supports output frequencies ranging from 3.125 MHz to 900 MHz, utilizing differential LVPECL output signals. The device features an on-chip crystal oscillator for reference frequency generation and can also accept an external LVCMOS-compatible reference input. This clock synthesizer includes a fully integrated PLL that minimizes frequency overshoot and offers a serial 3-wire programming interface alongside a parallel programming interface for configuration. The PLL's VCO operates within a frequency range of 400 to 900 MHz, and the output can be divided by configurable ratios of 1, 2, 4, or 8, ensuring a 50% duty cycle. The MPC92439EIR2 is available in both 28-Lead PLCC and 32-Lead LQFP packages, with Pb-free options, and is compatible with existing designs using the MC12439 and MPC9239. The device is rated for operation in an ambient temperature range of 0¬8C to +70¬8C.
