NXP Semiconductors TDA8761
The TDA8761 is a 9-bit analog-to-digital converter (ADC) for professional video and digital video set box applications. It converts the analog input signal into 9-bit binary-coded digital words at a maximum sampling rate of 30 MHz. Its linearity performance ensures the required conversion accuracy in case of 256QAM demodulator concept and for all symbol frequencies.FEATURES
● 9-bit resolution● Sampling rate up to 30 MHz
● DC sampling allowed
● One clock cycle conversion only
● High signal-to-noise ratio over a large analog input frequency range (8.5 effective bits at 10 MHz full-scale input at fclk = 30 MHz)
● No missing codes guaranteed
● In range (IR) 3-state TTL output
● TTL compatible digital inputs and outputs
● Low-level AC clock input signal allowed
● External reference voltage regulator
● Power dissipation only 360 mW (typical)
● Low analog input capacitance, no buffer amplifier required
● No sample-and-hold circuit required. QUICK REFERENCE DATA SYMBOL VCCA VCCD VCCO ICCA ICCD ICCO AINL ADNL fclk(max) Ptot Note 1. fi = 11 MHz and fclk = 30 MHz; fi = 8 MHz and fclk = 20 MHz. ORDERING INFORMATION TYPE NUMBER TDA8761M PACKAGE NAME SSOP28
