MICROPROCESSOR CLOCK GENERATOR
MPC9819 PLL-based clock generator specifically designed Freescale Microprocessor Microcontroller applications including PowerPC PowerQUICC. This device generates microprocessor input clock other microprocessor system clocks four output frequencies. These frequencies include popular 133-MHz PCI/X frequencies. device offers five low-skew clock outputs plus three reference outputs. clock input reference derived from external source addition 25-MHz crystal on-chip crystal oscillator. extended temperature range MPC9819 supports telecommunication networking requirements. Features LVCMOS outputs processor other system circuitry Buffered 25-MHz reference clock outputs Crystal oscillator external reference input 25-MHz input reference frequency Selectable output frequencies include: 100, 125, cycle-to-cycle period jitter Package: 20-lead SSOP 3.3-V supply Supports computing, networking, telecommunications applications Ambient temperature range: -40°C +85°C

MPC9819 OPERATION
Crystal Oscillator MPC9819 features fully integrated Pierce oscillator minimize system implementation costs. Other than addition 25-MHz crystal, external components required.The crystal selection should MHz, parallel resonant type with load specification Crystals with load specification used, however, Table Crystal Specifications

reference frequency higher than specified MHz. Externally supplied capacitors both XTAL_IN XTAL_OUT pins used trim frequency desired. crystal should located close MPC9819 XTAL_IN XTAL_OUT pins possible avoid board level parasitic.
Power Supply Bypassing MPC9819 should have pins bypassed with 0.01 capacitors minimum capacitor overall package. capacitors should located close SSOP pins possible.
External Clock Source external reference source applied XTAL_IN pin. this mode operation, XTAL_OUT should left floating.
