DESCRIPTION
The DS10730-10A is a specially programmed and tested DS1073Z in an 8-pin SO (0.05in) package. The
device is configured internally and specified like a standard DS1073Z with two exceptions. The divider
chain is bypassed and the master oscillator is set to generate a 94MHz to 100MHz square-wave output on
pin 1. For AC and DC characteristics and specifications for the device, refer to the data sheet for the
standard DS1073Z. Exceptions to these specifications in this document hold precedence over the DS1073
data sheet specifications.

BLOCK DIAGRAM
The DS1073Z-10A is configured for a single, 97MHz output on pin 1 (OUT). The device is optimized for
use with the Focus Enhancements FS-460 SDRAM clock input. The pin 2 reference output (OUT0 on the
standard DS1073) is disabled. Pins 3 and 4 (V
CC
and GND, respectively) provide inputs for power. Pin 5
(
PDN
) is a control input that disables the master oscillator when low. Pin 6 (OE) is a control input, which
disables the pin 1 (OUT) output buffer when low. Pins 5 and 6 should be tied to V
CC
if not used. Pins 2, 7,
and 8 should be left open.

CONFIGURATION
Figure 2 shows a typical configuration for the DS1073Z-10A. If OE and
PDN
are not used, they should be
tied to V
CC
.
All other unused pins (DNC) should be left open. A decoupling capacitor is required for the
application and will vary in value depending on board layout and construction.
