Description
The Fairchild RC7105 is a low-voltage, thirteen-output clock
buffer. The skew between any two outputs is less than 250 ps
and the buffers can be individually enabled or disabled by
programming via the I2C serial interface. Output buffer
impedance is approximately 15
which is ideal for driving
SDRAM DIMMs.
