BURST LOCK CLOCK GENERATOR

The µPC1862 is an LSI incorporating a PLL circuit to generate nfSC clocks (fSC: color subcarrier frequency), ideal for the processing of digital video signals as in extended definition television (EDTV) systems.

FEATURES
• VCO is incorporated.
• Horizontal and vertical sync separation circuits are incorporated (with output pins).
• Horizontal and vertical sync output pulses (TTL level)
• ACC amplifier and killer detector circuits are incorporated.
• 1/4 and 1/8 (1/2 × 1/4) frequency dividers are incorporated.
• fSC phase control circuits is incorporated.
• Applicable to both NTSC and PAL systems.
• Possible to input burst gate pulse from external
