STLC2500A

Electrical characteristics

7/37

2.3

I/O specifications

The I/Os comply with the EIA/JEDEC standard JESD8-B.

Note:

X is the source/sink current under worst-case conditions according to the drive capabilities

(see Chapter 6)

2.4

Clock specifications

The STLC2500A supports, on the same input pin, the system clock both as a sine wave

clock and as a digital clock (see

Table 14 for selection). The system clock section is powered

by VDD_CLD (G08 and H09). The voltage range for VDD_CLD is the same as for

VDD_IO_A.
