TDA8754
Datasheet
General description
The TDA8754 is a complete triple 8-bit ADC with an integrated PLL running up to 270 Msample/s and analog preprocessing functions (clamp and PGA) optimized for capturing RGB/YUV graphic signals.
The PLL generates a pixel clock from inputs HSYNC and COAST.
The TDA8754 offers full sync processing for sync-on-green applications. A clamp signal may be generated internally or provided externally.
The clamp levels, gains and other settings are controlled via the I2C-bus interface.
This IC supports display resolutions up to QXGA (2048 x 1536) at 85 Hz.
Features
- 3.3 V power supply
- Temperature range from -10Cel to +70Cel
- Triple 8-bit ADC:
- 0.25 LSB Differential Non-Linearity (DNL)
- 0.6 LSB Integral Non-Linearity (INL)
- Analog sampling rate from 12 Msample/s up to 270 Msample/s
- Maximum data rate:
- Single port mode: 140 MHz
- Dual port mode: 270 MHz
- 3.3 V LV-TTL outputs
- PLL control via I2C-bus:
- 390 ps PLL jitter peak to peak at 270 MHz
- Low PLL drift with temperature (2 phase steps maximum)
- PLL generates the ADC sampling clock which can be locked on the line frequency from 15 kHz to 150 kHz
- Integrated PLL divider
- Programmable phase clock adjustment cells
- Three clamp circuits for programming a clamp code from -24 to +136 by steps of 1 LSB (mid-scale clamping for YUV signal)
- Internal generation of clamp signal
- Three independent blanking functions
- Input:
- 700 MHz analog bandwidth
- Two independent analog inputs selectable via I2C-bus
- Analog input from 0.5 V to 1 V (p-p) to produce a full-scale ADC input of 1 V (p-p)
- Three controllable amplifiers: gain control via I2C-bus to produce full-scale peak-to-peak output with a half LSB resolution
- Synchronization:
- Frame and field detection for interlaced video signal
- Parasite synchronization pulse detection and suppression
- Sync processing for composite sync, 3-level sync and sync-on-green signals
- Polarity and activity detection
- IC control via I2C-bus serial interface
- LQFP144 and LBGA208 package:
- LBGA208 package pin-to-pin compatible with TDA8756
