TA8772AN
PAL / SECAM / NTSC BASE BAND 1H DELAY SYSTEM FOR COLOR TV OR VCR
TA8772AN TOSHIBA BIPOLAR LINEAR INTEGRATED CIRCUIT SILICON MONOLITHIC
TA8772AN PAL / SECAM / NTSC BASE BAND 1H DELAY SYSTEM FOR COLOR TV OR VCR
The TA8772AN has two chips, a bipolar chip and a CCD chip, in a
package.
CCD chip consist of two delaylines which operate to delay R-Y
and B-Y signal. Bipolar chip operate to control the signals which
is processed by CCD stage.
FEATURES
Bipolar stage AGC circuit (For correcting output level) L.P.F. (For reducing CCD clock) DC clamp circuit (For reducing the difference of DC l vel between delay signal and direct
ignal.) Mode SW (For control output signal by PAL, NTSC or SECAM ident) 225fH VCO circuit (For making CCD clock)
CCD stage CCD drive circuit Sample & Hold circuit Input bias circuit Synctip clamp circuit (This device’s dynamic range bear no relation to change of APL on adopt this circuit) Delay time of 1H consist of supply 225fH clock.
TOTAL This device can operate by the smallest external parts because of include CCD drive circuit, bias generator
circuit and output amplifier for support CCD circuit.
