CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation

of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied.

Electrical Specifications TA = +25oC, VCC = 12V, VS = 2.85V, VC = 2.85V, VAB = VPB = VCC, VB adjusted for V18 = 6.3V, CX adjusted

for FOSC = 4.43361875MHz, Sandcastle: VBG = 8.0V, VBLANK = 3.5V - Burst Gate centered on Burst.

These conditions exist except as otherwise noted. See Figure 19 for test circuit

UNITS

Luma Input Signal = 30% Sync.

Luma Input Signal: 0.5VP-P (30% Sync) modulated CW

Adj. modulation frequency for -3dB at color outputs.

For Control Characteristics, See Figures 1 and 2.

Luma Input Signal: 0.5VP-P (30% Sync)

VB 0V - 5V,Measured at Pin 18 black level.

See Figures 1 and 2.

Luminance Input: 0.5VP-P (30% Sync), for Control Characteristics.

See Figure 3

Luminance Input: 0.5VP-P (30% Sync), VC = 0.5V - 5V measure

Pin 18 black level to maximum white level. See Figure 4.

Luminance Input: 0.5VP-P (30% Sync), VC = 5V, read black

level to peak white. See Figures 5 and 6.

Measure Burst level at Pin 4.

Chroma Input: Burst = 100mVP-P, Chroma = 220mVP-P.

Luminance Input: 0.35VP-P, VS adjusted for Chroma at

Pin 18 = 2VP-P. VC is adjusted for luminance at Pin 18 = 2VP-P,

VC is again adjusted for luminance of +6 and -9dB.

Then read chroma percentage difference. See Figure 9.
