110B0IBTI5TMS5PMS ASDPCS ADC
BL1B2L0182H08H
GENERAL DESCRIPTION
FEATURES
The BL1208H is a CMOS 10-bit A/D converter for
video applications. It is a three-step pipelined A/D
converter which consists of sample & hold, three
multiplying DACs, a 4-bit flash adc and three 3-bit
flash adcs.
The maximum conversion rate of BL1208H is 5MSPS
and supply voltage is 5V single.

STCB
The A/D converter does data conversion when STCB(Start of Conversion Bar) signal is just "HIGH".
Otherwise, output data (DO[9:0]) keeps the current states.
The STCB signal should be changed during "Tsafe" with the "HIGH" level of the clock to operation as shown
in the main waveform.
3. Pipeline Delay
STCB
EOC
Pipeline Delay
After STCB goes "HIGH", the A/D converter requires the pipeline delay of 3 clock period to generate EOC
signal and data outputs.
