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. EconOscillator is a trademark of Dallas Semiconductor. 1 of 3 091202 DS1073Z-10A 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 (VCC 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 VCC if not used. Pins 2, 7, and 8 should be left open. Figure 1. DS1073Z-10A Block Diagram 2 of 3 DS1073Z-10A CONFIGURATION Figure 2 shows a typical configuration for the DS1073Z-10A. If OE and PDN are not used, they should be tied to VCC. 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. Figure 2.
