Costas Loop

PSK Demodulation - Part 1 (PDF) - Scroll down to the section on Costas loops. Also covers variations of the Costas loop, and the remodulator.

The Costas Loop - An Introduction (PDF) - A good tutorial, but focuses on a digital/software implementation.

Digital PLL Design & Theory

Introduction To Phase-Lock Loop System Modeling (PDF) - By Wen Li and Jason Meiners. Brief S-domain analysis and design equations for a second order PLL, in both a linear and digital implementation.

Interactive Digital PLL Design - Online program that generates Java code for the PLL, C code for the loop filter. (Why not C for both?) Includes frequency, phase, impulse, and step response plots for the loop filter.

Phase Locked Loop (PLL) Tutorial

Phase Locked Loop Tutorial - By Tony van Roon, VA3AVR.

The Basics of PLL Frequency Synthesis (PDF) - A good introduction, but doesn't cover feedback theory, ringing, and damping issues.

Fractional / Integer-N PLL Basics (PDF) - Large 6 MB document. Perhaps a bit too technical to be called a tutorial, but well written and thorough. (Texas Instruments Technical Brief SWRA029.)

Phase Locked Loop Design Fundamentals (PDF) - This is a bit too technical to be called a tutorial. But if you ignore all the Laplace analysis, you can still learn a lot. (Motorola Application Note AN535.)
