LMH1983

The LMH1983 is a highly-integrated programmable audio/video (A/V) clock generator intended for broadcast and professional applications. It can replace multiple PLLs and VCXOs used in applications supporting SMPTE serial digital video (SDI) and digital audio AES3/EBU standards.
 
Features of the LMH1983 are:(1)four PLLs for simultaneous A/V clock generation;(2)3 x 2 video clock crosspoint;(3)flexible PLL bandwidth to optimize jitter performance and lock time;(4)soft re-synchronization to new reference;(5)digital holdover or free run on loss of reference;(6)status flags for loss of reference, and loss of PLL lock;(7)3.3V single supply operation;(8)I2C interface with address select pin (3 states).

The absolute maximum ratings of the LMH1983 can be summarized as:(1):the parameter is ESD tolerance human body model,the rating is 2500,the unit is V;(2):the parameter is ESD tolerance machine model,the rating is 250,the unit is V;(3):the parameter is ESD tolerance charge-device model,the rating is 750,the unit is V;(4):the parameter is supply voltage, VDD,the rating is 3.6,the unit is V;(5):the parameter is input voltage (any input),the rating is -0.3 to VDD+0.3,the unit is V;(6):the parameter is output voltage (any output),the rating is -0.3 to VDD+0.3,the unit is V;(7):the parameter is junction temperature,the rating is +150,the unit is ;(8):the parameter is storage temperature,the rating is -65 to +150,the unit is ;(9):the parameter is thermal resistance (JA),the rating is 33,the unit is /W.
