Description

The TLC2940 is a high-performance analog voltage-controlled oscillator (VCO) using Texas Instruments 0.8-µm CMOS process. The VCO oscillating operation can be performed by an external bias resistor connected to the internal oscillation circuitry, and the oscillation frequency range is set by this bias resistor. The lock frequency range of TLC2940 for PLL applications is from 35 MHz to 75 MHz (over operating free-air temperature range,VDD= 5 V ±5%), and from 28 MHz to 50 MHz (over operating free-air temperature range, VDD= 3 V ±5%).
The stable analog PLL can be configured within these frequency ranges.

The TLC2940 is available in an 8-pin TSSOP surface-mount package.

The PLL block of TLC2940 is configured using a counter, a required LPF, and a phase frequency detector (PFD).
