GENERAL DESCRIPTION
The SPT9400 is a triple video line driver chip that takes
standard Y/C analog inputs and provides simultaneous Y/C
and composite video analog outputs for driving 75
Internal summing of the Y and C inputs is performed to
produce composite video output. It is possible to achieve
composite output on both the Y and CVBS outputs simulta-
neously by inputting a composite signal on the Y input. The
luminance input is clamped at 1.25 V and amplified 6 dB to
produce a 2 V

The SPT9400 features a standby (active low) mode that
draws only 113 W of power. Nominal power dissipation (no
input) is typically 168 mW. It requires a single +5 V supply,
operates over the commercial temperature range (0 to +70 C)
and is available in a very small (5.0 x 4.4 mm) 12-lead Shrink
Small Outline Package (SSOP).
