MPC92439 REVISION 4 OCTOBER 27, 2009
LVCMOS Control Inputs (FREF_EXT, POWER_DOWN, XTAL_SEL, P_LOAD, S_LOAD, S_DATA, S_CLOCK, M[0:8], N[0:1]. OE)
Differential Clock Output F
Test and Diagnosis Output TEST
Supply Current
1. Inputs have pull-down resistors affecting the input current.
2. Outputs terminated 50Ω to V
1. AC characteristics apply for parallel output termination of 50Ω to V
2. The input frequency f
3. The frequency of S_CLOCK is limited to 10 MHz in serial programming mode. S_CLOCK can be switched at higher frequencies when used
4. Maximum cycle jitter measured at the lowest VCO frequency.
5. Maximum period jitter measured at the lowest VCO frequency.
