CDCE62005RGZR from Texas Instruments, in a VQFN-48-EP(7x7). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VCC_IN_SEC power_in 3.3-V supply for the secondary reference input buffer and circuitry.
2 SEC_REF- input Universal input buffer (LVPECL, LVDS) negative input for the secondary reference clock; for LVCMOS input on SEC_REF+, connect through 1-kΩ resistor to GND.
3 SEC_REF+ input Universal input buffer (LVPECL, LVDS, LVCMOS) positive input for the secondary reference clock.
4 REG_CAP1 passive Capacitor connection for the internal regulator; connect to a 10-µF capacitor (X5R or X7R).
5 VCC1_PLL power_in 3.3-V PLL supply voltage for the PLL circuitry (filter required).
6 U4P output Main output 4 positive; user-definable as LVPECL, LVDS or LVCMOS.
7 U4N output Main output 4 negative; user-definable as LVPECL, LVDS or LVCMOS.
8 VCC_OUT power_in 3.3-V supply for the output buffers and output dividers.
9 U3P output Main output 3 positive; user-definable as LVPECL, LVDS or LVCMOS.
10 U3N output Main output 3 negative; user-definable as LVPECL, LVDS or LVCMOS.
11 VCC_OUT power_in 3.3-V supply for the output buffers and output dividers.
12 Power_Down input Active-low power-down input with internal 150-kΩ pull-up; SPI_LE must be high for the rising edge to load the EEPROM.
13 AUX OUT output Auxiliary LVCMOS-level output programmable via SPI to be driven by Output 2 or Output 3.
14 SYNC input Active-low sync mode input with internal 150-kΩ pull-up.
15 VCC_AUXOUT power_in 3.3-V supply to power the AUX_OUT circuitry.
16 U2P output Main output 2 positive; user-definable as LVPECL, LVDS or LVCMOS.
17 U2N output Main output 2 negative; user-definable as LVPECL, LVDS or LVCMOS.
18 VCC_OUT power_in 3.3-V supply for the output buffers and output dividers.
19 U1P output Main output 1 positive; user-definable as LVPECL, LVDS or LVCMOS.
20 U1N output Main output 1 negative; user-definable as LVPECL, LVDS or LVCMOS.
21 VCC_OUT power_in 3.3-V supply for the output buffers and output dividers.
22 SPI_MISO tri_state 3-state LVCMOS serial data output to the SPI bus, enabled when SPI_LE is asserted low.
23 SPI_MOSI input LVCMOS serial control data input for the SPI bus with internal 150-kΩ pull-up.
24 SPI_CLK input LVCMOS serial control clock input for the SPI bus with hysteresis and internal 150-kΩ pull-up.
25 SPI_LE input LVCMOS latch enable input for the SPI with hysteresis and internal 150-kΩ pull-up; it must be logic 1 before Power_Down toggles low-to-high for EEPROM load.
26 VCC_OUT power_in 3.3-V supply for the output buffers and output dividers.
27 U0P output Main output 0 positive; user-definable as LVPECL, LVDS or LVCMOS.
28 U0N output Main output 0 negative; user-definable as LVPECL, LVDS or LVCMOS.
29 VCC_OUT power_in 3.3-V supply for the output buffers and output dividers.
30 TESTOUTA passive Reserved analog pin; pull down to GND via a 1-kΩ resistor.
31 REF_SEL input External input reference select with internal 150-kΩ pull-up, active only when auto reference select mode is off.
32 VCC_OUT power_in 3.3-V supply for the output buffers and output dividers.
33 TEST_MODE input Should be tied high or left unconnected.
