2 / 28 page 1999 Sep 21 2 Philips Semiconductors Product specification 18 Msps, 10-bit analog-to-digital interface for CCD cameras TDA8784 FEATURES • Correlated Double Sampling (CDS), AGC, 10-bit ADC and reference regulator included, adjustable bandwidth (CDS and AGC) • Fully programmable via a 3-wire serial interface • Sampling frequency up to 18 MHz • AGC gain from 4.5 to 34.5 dB (in 0.1 dB steps) • CDS programmable bandwidth from 4 to 120 MHz • AGC programmable bandwidth from 4 to 54 MHz • Standby mode available for each block for power saving applications (20 mW typical) • 6 dB fixed gain analog output for analog iris control • 8-bit and 10-bit DAC included for analog settings • Low power consumption of only 483 mW typical • 5 V operation and 2.5 to 5.25 V operation for the digital outputs • TTL compatible inputs, TTL and CMOS compatible outputs. APPLICATIONS • CCD camera systems. GENERAL DESCRIPTION The TDA8784 is a 10-bit analog-to-digital interface for CCD cameras. The device includes a correlated double sampling circuit, AGC and a low-power 10-bit Analog-to-Digital Converter (ADC) together with its reference voltage regulator. The AGC and CDS have a bandwidth circuit controlled by on-chip DACs via a serial interface. A 10-bit DAC controls the ADC input clamp level. An additional 8-bit DAC is provided for additional system controls; its output voltage range is 1.4 V (p-p) which is available at pin OFDOUT. ORDERING INFORMATION TYPE NUMBER PACKAGE NAME DESCRIPTION VERSION TDA8784HL LQFP48 plastic low profile quad flat package; 48 leads; body 7 × 7 × 1.4 mm SOT313-2 |
