• Manufacturer: Cirrus Logic Inc

Specifications of CRD-5378

• Description/function: Audio D/A
• Operating Supply Voltage: 3.3 V
• Product: Audio Modules
• Supply Current: 100 mA
• For Use With/related Products: CS3302A, CS5373A, CS5378
• Lead Free Status / RoHS Status: Lead free / RoHS Compliant

CS5378 PLL input frequency is specified at reset by the state of the GPIO[4..6]:PLL[0..2] pins, as detailed
in the CS5378 data sheet.
If no external system clock is supplied to CRD5378, the CRD5378 can select a PLL input clock from a
local oscillator. Using a clock divider, the on-board oscillator produces 1.024 MHz, 2.048 MHz, 4.096 MHz
and 32.768 MHz clock outputs that can be applied to the CS5378 CLK input.
