LM1880 Datasheet PDF - National Semiconductor No-Holds Vertical/Horizontal Specs

LM1880 - No-Holds Vertical/Horizontal

Datasheet Summary

Description

The LM1880 uses compatible Linear I2L technology to produce the first T V horizontal and vertical processing system which completely eliminates the hold controls The heart of the system is a precision 32 times horizontal frequency VCO which is designed to use a low-cost ceramic resonator as a tuning

LM1880 No-Holds Vertical Horizontal June 1987 LM1880 No-Holds Vertical Horizontal General Description The LM1880 uses compatible Linear I2L technology to produce the first T V horizontal and vertical processing system which completely eliminates the hold controls The heart of the system is a precision 32 times horizontal frequency VCO which is designed to use a low-cost ceramic resonator as a tuning element The VCO signal is divided down in the horizontal section to produce a pre-driver output which is locked to negative sync by means of an on-chip phase detector The vertical output ramp is injection-locked by vertical sync subject to a sync window derived from the vertical countdown section A gate pulse centered on the chroma burst is also provided Features Y No frequency set-up requi
