High-Speed ADC (HSADC)
37.1 Overview
The high-speed ADC block is designed for driving the linear image scanner sensor (for
example, TOSHIBA TCD1304DG linear image scanner sensor). It can also support some
other general user cases which need to sample analog source with up to 2 Msps data rate
and then move the sample data to the external memory. The high-speed ADC block integrates
a 12-bit analog ADC block. This analog ADC block can support up to 2 Msps sample rate.
In order to improve the flexibility, the high-speed ADC block can co-work with PWM block
which can generate driving signals of external device such as the linear image scanner
sensor. The PWM can also generate trigger signal which is synchronous with high-speed
ADC block to start the conversion of ADC. An APBH-DMA channel is connected to the
high-speed ADC block to move the sample data from the asynchronous FIFO inside the
high-speed ADC block to the external memory.
