FUNCTIONAL DESCRIPTION
PIN DESCRIPTIONS
The PDU54-series device is a 4-bit digitally programmable delay line. The
delay, TDA, from the input pin (IN) to the output pin (OUT) depends on the
address code (A3-A0) according to the following formula:
TDA = TD0 + TINC * A
IN Signal Input
OUT Signal Output
A3-A0 Address Bits
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
100ps through 3000ps, inclusively. The address is not latched and must remain asserted during normal
operation.
SERIES SPECIFICATIONS
• Total programmed delay tolerance: 5% or 40ps,
whichever is greater
• Inherent delay (TD0): 3.3ns typical
• Address to input setup (TAIS): 2.9ns
• Operating temperature: 0° to 85° C
• Temperature coefficient: 100PPM/°C (excludes TD0)
• Supply voltage VEE: -5VDC ± 0.7V
• Power Supply Current: -300ma typical (50Ω to -2V)
• Minimum pulse width: 3ns or 10% of total delay,
whichever is greater
• Minimum period: 8ns or 2 x pulse width, whichever
is greater
