SEi - Radiation Hardened 54HC4046RP
Phase-Locked Loop
Specifications and design are subject to change without notice.
S
Ei’s 54HC4046RP (RP for RAD-PAK®) high speed Phase Lock Loop microcircuit features a 100 kilorad (Si)
total dose tolerance. This device uses advanced CMOS technology to obtain high frequency operation. The
54HC4046RP contains a low power linear voltage controlled oscillator (VCO), a source follower, and three phase
comparators. The three phase comparators have a common signal input and a common comparator input. The
signal input has a self biasing amplifier allowing signals to be either capacitively coupled to the phase compara-
tors with a small signal or directly coupled with standard input logic levels. Any one of the three comparators
feeds an external filter network, which in turn feeds the VCO input. This input is a very high impedance CMOS
input that also drives the source follower. An inhibit pin is provided to disable the VCO and the source follower,
providing a method of putting the IC in a low power state. Capable of surviving space environments, the
54HC4046RP is ideal for many satellite, spacecraft, and space probe missions. The radiation hardened RAD-
PAK® technology incorporates radiation shielding in the microcircuit package. The 54HC4046RP is available in
Class S packaging and screening.
