2 / 36 page  2000 Jan 10 2 Philips Semiconductors Preliminary specification Triple high-speed Analog-to-Digital Converter 110 Msps (ADC) TDA8752B FEATURES • Triple 8-bit ADC • Sampling rate up to 110 MHz • IC controllable via a serial interface, which can be either I2C-bus or 3-wire, selected via a TTL input pin • IC analog voltage input from 0.4 to 1.2 V (p-p) to produce a full-scale ADC input of 1 V (p-p) • 3 clamps for programming a clamping code between −63.5 and +64 in steps of 1⁄2LSB • 3 controllable amplifiers: gain controlled via the serial interface to produce a full scale resolution of 1 ⁄2LSB peak-to-peak • Amplifier bandwidth of 250 MHz • Low gain variation with temperature • PLL, controllable via the serial interface to generate the ADC clock, which can be locked to a line frequency of 15 to 280 kHz • Integrated PLL divider • Programmable phase clock adjustment cells • Internal voltage regulators • TTL compatible digital inputs and outputs • Chip enable high-impedance ADC output • Power-down mode • Possibility to use up to four ICs in the same system, using the I2C-bus interface, or more, using the 3-wire serial interface • 1.1 W power dissipation. APPLICATIONS • R, G and B high-speed digitizing • LCD panels drive • LCD projection systems • VGA and higher resolutions • Using two ICs in parallel, higher display resolution can be obtained; 200 MHz pixel frequency. GENERAL DESCRIPTION The TDA8752B is a triple 8-bit ADC with controllable amplifiers and clamps for the digitizing of large bandwidth RGB signals. The clamp level, the gain and all of the other settings are controlled via a serial interface (either I2C-bus or 3-wire serial bus, selected via a logic input). The IC also includes a PLL that can be locked to the horizontal line frequency and generates the ADC clock. The PLL jitter is minimized for high resolution PC graphics applications. An external clock can also be input to the ADC. It is possible to set the TDA8752B serial bus address between four fixed values, in the event that several TDA8752B ICs are used in a system, using the I2C-bus interface (for example, two ICs used in an odd/even configuration). ORDERING INFORMATION TYPE NUMBER PACKAGE SAMPLING FREQUENCY (MHz) NAME DESCRIPTION VERSION TDA8752BH/8 QFP100 plastic quad flat package; 100 leads (lead length 1.95 mm); body 14 × 20 × 2.8 mm SOT317-2 110 |
