FUNCTIONAL DESCRIPTION
PIN DESCRIPTIONS
The PDU1032H-series device is a 5-bit digitally programmable delay line.
The delay, TDA, from the input pin (IN) to the output pin (OUT) depends
on the address code (A4-A0) according to the following formula:
IN Signal Input
OUT Signal Output
A0-A4 Address Bits
ENB Output Enable
TDA = TD0 + TINC * A
VEE -5 Volts
GND Ground
where A is the address code, TINC 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 20ns, 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
• Total programmed delay tolerance: 5% or 2ns,
whichever is greater
• Inherent delay (TD0): 5.5ns typical for dash numbers
up to 5, greater for larger #’s
• Setup time and propagation delay:
Address to input setup (TAIS): 3.6ns
Disable to output delay (TDISO): 1.7ns typical
• Operating temperature: 0° to 70° C
• Temperature coefficient: 100PPM/°C (excludes TD0)
• Supply voltage VEE: -5VDC ± 5%
• Power Dissipation: 615mw typical (no load)
• Minimum pulse width: 20% of total delay
