TLC2940 - Texas Instruments

TLC2940 HIGH-PERFORMANCE CMOS VOLTAGE-CONTROLLED OSCILLATOR

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 for PLL applications i.

temperature range, VDD = 3 V ± 5%). The stable analog PLL can be configured within these frequency ranges. The device is available in an 8-pin TSSOP surface-mount package. The PLL block is configured using a counter, a required LPF, and a phase frequency detector (PFD). AVAILABLE OPTIONS PACKAGE TA TSSOP (PW)
