8-output, PCIe Gen 1 to Gen 7 compliant, BAW reference-less clock generator, clock mux and buffer

LMK3H2104

and LMK3H2108 are BAW-based clock generators that do not require

any external XTAL or XO. The devices can be used as PCIe clock generators or general purpose

clock generators. The 2 FODs (Fractional Output Divider) provide frequency flexibility, low

power and low jitter at the same time.

LMK3H2104

has up to 4 differential outputs plus 2 LVCMOS outputs or up to 10 LVCMOS outputs. LMK3H2108 has up to 8 differential outputs or 16 LVCMOS outputs.

LMK3H2104

has one clock input and LMK3H2108 has three clock inputs. The

clock inputs provide clock multiplexing and buffering ability. Each output bank can

independently select any clock source.

The GPI and GPIO pins provide additional control

flexibility. These pins can be configured as individual OE, grouped OE, I2C address

selection, OTP page selection, PWRGD/PWRDN#, status output and other functions.

The device supports one-time programmable (OTP)

non-volatile memory which can be customized and factory preprogrammed.
