FUNCTIONAL DESCRIPTION
The PDU1064H-series device is a 6-bit digitally programmable delay line. The delay, TD_A, from the input
pin (IN) to the output pin (OUT) depends on the address code (A5-A0) according to the following formula:
TD_A = TD₀ + T_INC * A
where A is the address code, T_INC is the incremental delay of the device, and TD₀ is the inherent delay of
the device. The incremental delay is specified by the dash number of the device and can range from
0.5ns through 10ns, inclusively. The enable pin (ENB) is held LOW during normal operation. When this
signal is brought HIGH, OUT is forced into a LOW state. The address is not latched and must remain
asserted during normal operation.
SERIES SPECIFICATIONS
DASH NUMBER SPECIFICATIONS
• Total programmed delay tolerance: 5% or 2ns,
whichever is greater
Inherent delay (TD₀): 12ns typical
• Setup time and propagation delay:
Address to input setup (T_AIS): 3.6ns
Disable to output delay (T_DISO): 1.7ns typical
• Operating temperature: 0° to 70° C
• Temperature coefficient: 100PPM/°C (excludes TD₀)
• Supply voltage V_EE: -5VDC ± 5%
• Power Dissipation: 925mw typical (no load)
• Minimum pulse width: 20% of total delay
