32 kHz and 24 MHz Clock Generator with Precision 32 kHz Input
Features
CY2040-2/3
Cypress Semiconductor Corporation
Document #: 38-07122 Rev. *A
3901 North First Street
San Jose
CA 95134

Precision RTC 32 kHz and 24 MHz output
Power-down mode (32 kHz on) is < 50 uA
Suspend mode (V24M = off) is typically 5 uA
Low RMS period Jitter (< 40 ps)
16-pin TSSOP package
3.3V + 5% Voltage Supply
CY2040-2 multiplier 32.000 kHz × 750 = 24.0 MHz
(requires a single 32.000 kHz crystal)
CY2040-3 enables the 32 kHz and 24.0 MHz oscillators
(requires a 32.768 kHz and 24.000 MHz crystal)
