TVP2002

The TVP2002 is one kind of clock driver with some features and maximum ratings.It interfaces a 10 KH-ECL oscillator operating from a single 5-V supply to the TCL34058,generating the necessary clock and control signals.The clock output may be divided by 3,4,5,or 8 to generate the load signal.The load signal is also divided by 2 and 4 for clocking video timing logic,etc.A second load signal may be synchronously or asynchronously sontrolled to enable starting and stopping of the VRAM clock.The TVP2002 also optionally configures the pipeline delay of the TLC34058 to a fixed pipeline delay.An on-chip 1.235-V reference is provided and may be used to provide the reference voltage for the color palette.

The features of TVP2002 are:(1)135-MHz operation;(2)differential ECL clock generation;(3)divide by 3,4,5,or 8 of the clock;(4)divide by 2 and 4 of the load;(5)resets pipeline delay of the TLC34058;(6)1.235-V voltage reference output;(6)5-V single power-supply operation;(7)28-pin PLCC(FN) package;(8)low power consumption...400 mW max;(9)designed to be interchangeable with brooktree bt438.

The TVP2002 also has some absolute maximum ratings over operating free-air temperature range(unless otherwise noted):(1)supply voltage,Vcc:7 V;(2)input voltage,Vi:7 V;(3)operating free-air temperature range,Ta:0°C to 70°C;(4)storage temperature range:-65°C to 150°C.
