STV0681 Hardware Interfaces

STV0681

24/44

ADCS 7283313C

4.6

Quartz crystal

Regardless of the sensor type or anti-flicker requirements, the sensor + STV0681 chipset operates

from a single 12MHz fundamental quartz crystal. For specification requirements, see

Table 13.

STV0681 includes an on-chip low jitter PLL. For PLL characteristics, see

Table 12.

4.7

Numeric LCD interface

STV0681 supports a 2-digit LCD panel only, for alpha-numeric display.

4.7.1

LCD types

STV0681 connects to a non multiplexed, direct drive LCD with 2 x 7 segments. Many LCD types are

compatible with this interface. The LCD refresh frequency is 34.7Hz.

4.7.2

LCD interface pinout

The convention for segment numbering is as follows: '0' connects to segment 'a', '1' connects to

segment 'b', and so on, where a to g are standard for all 7-segment displays, as well as an LCD

common output, giving fifteen signals in total.
